Shipping Magnets: Understanding the Rules

Shipping magnets safely might be a little more complicated than you realize.  In today’s age of instant gratification, there are still a few times that our products just can’t be shipped by air for overnight delivery. Graphic image of shipping magnets by air

Because of their ability to interfere with the navigation and electronic equipment on planes, many industrial magnets, magnetic assemblies and strong rare earth magnets cannot be shipped via air.

Whenever possible we prefer to ship magnets by ground transportation, because magnets shipped via air will be classified as Dangerous Goods if not properly packed to block their magnetism.  Additionally, many carriers will not accept magnets for air shipments.

There are few guidelines that dictate how magnets are packaged and what is deemed safe to ship by air.

The Rules for Shipping Magnets

Magnets and magnetic devices can be shipped by air if the following criteria are met:

  • “For carriage by aircraft, any package which has a magnetic field of more than 0.00525 gauss measured at 4.5 m (15 feet) from any surface of the package.”  – Pipeline and Hazardous Materials Safety Administration, Dept. of Transportation (PHMSA) rule 173.21 (d). http://phmsa.dot.gov/hazmat
  • If the maximum field strength observed at 7 feet is less than .002 gauss, or there is no significant compass deflection, the package is not restricted as “Magnetized Material” per the FAA and the IATA .

Packing Magnets for Shipping

That can be a lot of magnetic field to block if you consider a magnet with 100 pounds of pull.  In some cases it can be accomplished by shielding the magnets with specially designed covers, by using padding or cardboard shredding, or by creating a steel lined box.  All of these take extra packing time and material, and add to the weight of the shipment.  Additional shipping fees will apply.

As expected, PHMSA and IATA also provide guidelines for packing magnets for air shipments.

  • IATA Packing Instruction 953 states “Magnetized material will be accepted only when:

(a) devices such as magnetrons and light meters have been packed so that the polarities of the individual units oppose one another;

(b) permanent magnets, where possible, have keeper bars installed;

(c) the magnetic field strength at a distance of 4.6 m (15 ft) from any point on the surface of the assembled consignment:

(1) does not exceed 0.418 A/m (0.00525 gauss), or

(2) produces a magnetic compass deflection of 2 degrees or less.

See Packing Instructions 953, IATA – http://www.iata.org/publications/dgr/Pages/index.aspx

  • The FAA and PHMSA both require training and ongoing documentation of training records for employees who package any dangerous goods articles.

Proper documentation and labeling must be provided for any shipment that will be classified as dangerous goods or magnetic materials.   We are experts in shipping magnets and will professionally handle the shipping process, including any documentation preparation.

However, if you plan to re-package or re-ship magnetic materials yourself, be aware that shipping magnets via air classifies them as Dangerous Goods, and as such, proper paperwork and labeling is required. Your carrier can provide you with these documents.

Shipping magnets probably isn’t something you’ve thought about, it’s okay, we do.   If you have questions about how your order will arrive, please contact our sales team for more information.

Handle With Care: Tips for Magnet Safety

Tip for magnet safetyMagnets might appear small and shiny, but don’t under estimate their strength.  Just like most things there are some common sense guidelines for handling magnets.  These tips for magnet safety can help prevent personal injury and property damage.

  • Wear gloves and take care when handling magnets.  Pinching, snapping or crushing can easily occur when a finger is caught between two attracting magnets. Many of our magnets come with plastic spacers just for this reason.
  • Wear protective eye wear.  Magnets are very brittle and pieces can easily chip or shatter if they accidentally snap together, sending shards flying.
  • Magnets are not toys.  Do not give to children to play with.
  • Do not swallow magnets. They can do severe damage to internal organs, resulting in surgery or death.
  • Magnets can interfere with pacemakers and other medical devices such as magnetic ports.  Avoid wearing badge magnets, decorative magnetic clips or similar items near the device.
  • Many magnets are coated with nickel to prevent corrosion.  People with nickel allergies should avoid prolonged handling of these magnets.
  • Always properly store and label industrial magnets.  Their extreme strength poses an added risk to users who may be unaware of the magnet’s capabilities.
  • Always store magnets in “Off” position or with shields, if available.
  • Take care in placing electronics, such a cell phones, near magnets to avoid damage.  Older electronics including computer diskettes, audio/video cassettes, credit cards or other magnetically stored media and electronic equipment. Magnets can alter or erase the important information stored on these devices.
  • Magnets affect compasses and navigational equipment. For this reason, we do not recommend shipping most magnets by air – without being properly packed and shielded strong magnets are classified as dangerous good for air transportation.  Refer to our shipping magnets page for additional information.

While many of magnets with low pull strength may not pose the same danger that very strong rare earth magnets do, it’s always a good idea to treat magnets with respect.  Safety first!

Creative Magnetic Projects Perfect for Celebrating Mom

Making Sentiment Button Magnets is an easily customizable magnet project that kids can help with – from start to finish. First, gather all the needed supplies, including colored or patterned paper, clear glass flat pebbles, spray adhesive, and small round magnets. We used half-inch diameter ceramic disc magnets, which are readily available at most craft or hardware stores.

What You Need 2

It takes just a few items to make this special magnet project for Mother’s Day.

 

Using a nickel as a template, cut the paper to fill the back of the pebble (small pictures would work great for this too). Add any sentiment at this point.  Then spray the flat side of the pebble with the adhesive and apply the paper design side down. Glue the magnet in the center of the paper and viola – you have a customized set of sentiment magnets!

 

Decorative Magnetic Frame

Moms love to display pictures of their kids and this small, decorative frame featuring a favorite picture makes a lovely gift. This project only requires leftover scraps of paper, ribbon and a small flower embMother's Day magnetic projects includes photo frames like this oneellishment. We used a neodymium disc magnet with adhesive to finish off this magnetic project.

 

First we printed the photo and trimmed it to size (this one is two inches square). Next, we matted it on card stock and added a contrasting boarder. Washi tape would also work great for this step. A simple brad holds the flower embellishment. The ribbon finishes off the frame and also hides the magnet, which was applied on the back left corner. Neodymium discs with adhesive are very strong and will easily hold through the fabric (allow 24 hours for full cure time).

Benefits of Magnetic Sign Holders for Merchandising

Creating the right retail environment involves taking into account every detail, including sign holders. The range of sign holders for merchandising can be overwhelming, and selecting the right sign holding system to best communicate sales and branding messaging is important to your overall retail environment. Magnetic sign holders provide many benefits from complimenting the décor to ease of simple installation. Photo of magnetic sign holders in front of a mannequin.

By definition, magnetic sign holders, frame holders, round base magnets, and hooks are repositionable sign holding systems, which are easily moved within a retail setting and not permanently attached to shelving or fixtures.

While that alone may sound attractive, here’s a few more benefits magnetic repositionable sign holders provide retailers.

  • Quick Change – Magnetic sign holders are repositionable and can easily be moved to a variety of locations within the store. Reorganizing aisles or placing new floor sets is as easy as picking up a sign holder and placing it in the new location – no tools required. In the case of some magnetic adjustable sign holders, accommodating a taller or shorter location is as simple as pushing a lever.
  • No Special Staff – Unlike certain systems that require outside design firms to install or change out heavy or unwieldy graphics, or even repair damage to walls or fixtures, magnetic sign holders can be set up and changed by the store’s own staff. Even when using magnetic hooks to hang signs from the ceiling, extender tools can be used to keep employees safely on the floor while changing out graphics.
  • Fits many environments – Magnetic sign holders come in such a wide range of sizes, styles and types that they can seamlessly compliment almost any retail décor. Repositionable sign holders have the advantage of accommodating seasonal decorating changes and branding updates; making the task easier and quicker for employees.
  • Cost effective – Available at a relatively low cost per unit, magnetic sign holders can be used over and over again. Reposition them where needed for maximum impact in the store. Simply change out graphics to reflect current sales, holiday promotions or new branding, and continue to utilize the existing sign holders. There is no additional investment in hardware.

 

Our knowledgeable magnetic solutions specialists can help you choose the right type of repositionable magnetic sign holders or frame holders for your P.O.P. or merchandising application. With over 80 different P.O.P. magnets, there is sure to be an option for your retail setting. Contact us for samples and solutions!

Printing Direct to Magnet: Achieving Quality Results

Printing direct to magnet is a cost effective method of creating high impact vehicle graphics, P.O.P. displays, calendars and other ad specialty items, portraits, decorative magnets, message boards, photos, way finding signs, temporary signage, and more. Achieving quality results from your printer and magnetic sheeting is essential for the success of every project.

 

Printing direct to magnet with the HP Latex 3000.

Printing direct to magnet with quality results doesn’t take an advanced degree, just a little extra time during setup. PrintMagnetVinyl on HP Latex 3000, HP certified.

Magnetic sheeting is considered a semi-rigid substrate, and, like all semi-rigid substrates, takes a little know-how to produce the best quality product. Here are some tips for printing direct to magnet.

 

  1. Choose the right top coat. Selecting the type of magnetic sheeting is critical, as different inks react differently with different coatings. PrintMagnetVinyl™ is a vinyl topcoat that is designed to work with solvent, eco-solvent, UV, and latex printers. For aqueous-based ink printers, PrintMagnet™ a magnetic sheeting with a paper topcoat, is an ideal match.
  2. Choose the correct thickness. For roll-fed wide format printers, thinner magnet can be advantageous as the weight of the magnet pulling through the machine can get quite heavy. Many printers prefer staying below 30-mil for this type of printer and have the best success with 20-mil. Sheet fed or flatbed printers can handle slightly thicker magnet. Be sure to check your owner’s manual for the recommended maximum thickness to ensure that the printer can handle the thickness of the magnet for the required application.
  3. Avoid strikes. As with other semi-rigid substrates, it’s important to steer clear of head strikes. In order to avoid damaging printheads, adjust the printer’s head height to the highest setting. Your owner’s manual provides information on the thickest material that it can handle in order to prevent head strikes.
  4. Make some space. As some printers may have metal platens, it is important to cover this piece to keep the magnet from sticking or catching during the printing process. A simple strip of heavy tape will do the trick, as will a thin piece a chip board. The point is to create a little air gap or space that prevents the magnet from attracting to the metal as it passes over.
  5. Raise it up. Elevating the roll of magnet sheeting in a way that gives a slightly straighter feed into the printer or lessens the steepness of the angle from the feed spindle to the printing area often provides better printing results. The goal is to prevent the magnetic sheeting from rippling, bunching up, or pulling too taught while feeding through the printing area. Check your owner’s manual for the maximum weight restrictions on the feed end of your printer.
  6. Slow and steady. Now isn’t the time to rush. Take the time to adjust the printer settings and be patient. Slowing your printer down and having patience is a necessity when printing on magnet. It is NOT a “set-up and walk away” type of printing job.

How To Select Magnetic Inventory Labels

Warehouse imageWith the unique challenges faced in business today, most warehouse and distribution centers face the added tasks of scalability, flexibility and easy navigation. Magnetic inventory labels, a relatively low-tech item, can provide a quick and re-positionable solution for shelving and storage areas.

As companies grow, reorganize, bring in new products, and discontinue old ones, magnetic inventory labeling makes sense as both the holders and the cards can be relocated with the product.

Master Magnetics offers four types of categories of magnetic inventory labels: Data card holders, magnetic strip with vinyl top coat, plain magnetic strip for pre-printed labels, and label holders

It’s important to fully understand the scope of the labeling project to determine which product will work best in your warehouse or storage application.

Some things to consider include:

  • Will you relabel shelving or items frequently? Seasonally?

    Magnetic Inventory Labels - Data Card Holder

    Magnetic Data Card Holder kit available in four standard widths.

If this is the case, then data card holders or labels holders make it easiest to simply relabel the magnet.

  • Are your labels generated by a bar code machine, RFID or by hand?

Pre-generated labels work best with any of the magnetic inventory label systems except for the vinyl topcoat. Be sure to take into account the size of label your machine generates and match it to the corresponding size magnetic label.

  • Is your warehouse racking or shelf storage smooth or is does it have a texture that might interfere with the gripping power of the magnet?

Any surface that isn’t smooth may need a thicker magnet to ensure the label stays put. Both the standard magnetic strip and the magnetic vinyl coated strip are available in different thickness.

  • Do aesthetics matter?

In areas that are customer-facing, label holders present a cleaner, more polished appearance.

Other considerations to take into account include determining if the labels should be pre-cut, score cut or uncut? Will  standard lengths and widths work in your environment, or do you require custom sizing?

Our seasoned team of magnetic solutions specialists can help you choose the right type of magnetic inventory label to help organize your space. Contact us for samples and solutions!

Tips for Taking Magnetic Vehicle Signs the Extra Mile

Image of magnetic vehicle sign on a work van.Magnetic vehicle signs are a popular way to give many businesses an inexpensive method of advertising. They can be printed locally by most sign shops, can be easily switched between vehicles and, with a little care, last several years.

In order to withstand highway speeds, most magnetic vehicle signs are printed on .030” magnetic sheeting. This ensures the magnet has enough sheer strength to stay on the car during driving. But selecting the right material is just part of the equation. Properly applying and maintaining your magnetic sign takes this investment the extra mile.

Application Tips
One of the appealing things about magnetic vehicle signs, is that there is no expert installation needed; just a few common sense tips.

  • Thoroughly clean and dry the vehicle surface where the magnet will be applied.
  • Ensure the magnetic sign is clean and free of any debris – especially if the sign has been stored and is being reapplied.
  • Select a smooth, flat, vertical, metal surface to apply the magnetic sign. Car doors are the most common spot for these signs.
  • The magnet being applied should be room temperature (at least 68 degrees F). Cold magnets become rigid, making them difficult to smoothly apply and strongly attach to the entire surface.
  • Beginning with a corner, gently place the magnet – letting it ‘grab’ the surface as it is placed.

Don’ts:
Ø Don’t drag the magnet across the surface of the car. If you need to reposition the sign, simply remove it by pulling back on a corner. This protects the finish of the vehicle.
Ø Don’t apply the magnet over rust, trim work, deep curves, or vinyl car wraps. These things create air gaps, which prevent the magnetic sheeting from fully gripping the metal. As a result, the sign is likely to fall off.
Ø Don’t trap water or grit between the magnet and vehicle surface. Not only does this create an air gap, but it can damage the finish of the vehicle.

 

Storage Tips
In between uses, take care to extend the life of your signs by showing your magnet a little love.

  • Keep magnetic vehicle signs, flat and dry.
  • Store where the temperature will not exceed 150 F (not in the trunk of a car).

Don’ts:
Ø Don’t store more than one sign with the magnet sides touching.
Ø Don’t store heavy items on the signs

 

Maintenance Tips
To prolong the life of the magnet and for the benefit of the vehicle, it’s ideal to periodically remove the sign and clean both the vehicle and magnet.

  • Magnetic signs can be cleaned with Windex or a gentle detergent. Dry thoroughly before reapplying.
  • Take care to avoid creasing or bending the corners of the sign during removal.
  • Ideally, magnetic signs should be removed prior to going through car washes to avoid damaging the graphics, trapping dirt and moisture between the magnet and car, or losing the magnetic sign altogether.

Science Fair Projects Featuring Magnets

Magnets make a fascinating topics for science fair projects,  as well as illustrating many basic principles of science and generating downright fun experiments.

As science fair projects begin in earnest, here is a collection of some of the best science fair projects or experiments involving magnets we’ve seen.

 

Illustration of the cross-sectiion of what a mag-lev train looks like.

Illustration from Science Buddies.

 1. Magnetic Levitation- Maglev trains have been big news in the past year. Explore the science behind the future of mass transit with basic (or not so basic) magnet levitation experimentation. Simple experiments show how magnets levitate using their repelling force. Science Buddies details a great experiment building a small maglev train. More advanced students can also build propulsion mechanisms with the train, or measure how other variables like temperature, weight and material selection affect the motion.

 

2.  Electromagnets- Homopolar motors are the simplest electric motors generating rotational movement; and are simple to create with basic components and magnets. In this link, see how to make a simple car using just a basic AA battery, two rare earth magnets and some foil. Other versions of this project include shaping wire to spin, or adding a screw or bolt into the configuration. Regardless of the setup, these experiments are excellent introduction to electromagnets and motors.

3.  Eat Iron – This simple experiment is visually amazing, involves searching out iron in ‘iron fortified’ food and might require a strong stomach. Cereals, and other iron-fortified foods, really do have iron added to their recipe, making them healthier for many. In this experiment, dissolving the cereal in water lets students see the exactly how much iron could be consumed as the magnet pulls the element away from the food. Compare types of cereal, breads, pastas, or snack bars. Visit Steve Spangler Science for more information on this experiment.

 

4.  Lenz’s Law – Explore Lenz’s Law with a stop watch, various thicknesses of copper tubes and magnets. This is a YouTube favorite, and for good reason – it’s a strong visual representation of eddy currents as they relate to a magnetic field. Education.com details a basic experiment, which can be expanded to add different materials, thicknesses of materials and strengths of magnets. Watch a video detailing this here.

 

These experiments can all be done with materials – including the magnets – found at your local hardware store or craft store. In some cases, complete kits are available from educational suppliers. If you’re looking for assistance with types of materials needed, our magnetic products specialists are available to assist.

If you, or your favorite student, has a magnetic science fair project or experiment, share the experience with us!
