Measuring Pull Strength

One method of determining the strength of a magnet is through pull strength.

Pull testing a magnet

Determining strength of a magnet through a pull test.

Pull strength is a reliable method of measuring the maximum strength, or holding power, that a magnet has before it is separated from ferrous material. It is measured in pounds or kilograms.

Magnetic assemblies are measured by the pounds of pull in a vertical test. Obviously, the higher the pull strength, the stronger the magnet. Permanent magnetic materials are commonly measured by grade.

The Process
We rate our magnetic assemblies by pounds of pull in a vertical test. Each magnet’s entire magnetic surface is tested against a .5” thick, ground steel plate. Beginning with a clean magnetic surface and a clean steel surface, the magnetic assembly to be tested is attached to the steel plate. A hook with the measuring device is attached to the magnet and it slowly pulls the magnet upward until enough force to break the magnet away from the plate has been created. The measuring device records the pounds pull. By repeating this test multiple times, we can establish an accurate reading and pounds pull rating for the magnetic assembly.

Pull tests are widely used across the industry and it’s common for magnetic assemblies to have a rating of pounds pull in order to provide users with accurate insight of the product’s capability.
However, it is important to note that pull strength will vary with:

  • differing thicknesses of steel (particularly less than .5”)
  • types of steel composition
  • coatings on the steel, including paint or grease
  • or uneven surface area, such as rust

Application Considerations
Choosing a magnetic assembly might be as straightforward as selecting the right pounds pull for your application. Considering things like how many poles are needed; if it there will be air gaps at any point on contact; how hot or wet the environment is; and the storage area can all affect the type of magnet best suited to a project.

We always recommend consulting with our magnetic solution specialists to help select the correct magnet for the application.

Going Fishing? Take a Magnet Too

Row Boat ready for fishing magnets

What to do when the fish just aren’t biting? Maybe it’s time to try angling for a different sort of catch.

Some fisherman routinely use fishing magnets, or strong retrieving magnets, to rescue items that fell out of the boat or off the dock, including tackle boxes, tools and even anchors that have come off their lines. Lost keys, too, have been retrieved with fishing magnets, using a little time and lot of patience.

Or, try using magnets as the bait and you might just reel in an attractive treasure. For some, this pastime is an exciting metal treasure hunt in the water. Fishing for sunken treasure along the floor of the lake or stream has turned up old coins, knives, safes, bikes, and even motorcycles and war relics.


Regardless of the reason for the use, there are a few things to keep in mind when using a fishing magnet.

Be sure to select a strong enough rope to thread through the eyebolt – it needs to be strong enough for the magnet, as well as any water current and the items being retrieved.   Likewise, attach the rope securely – such as with the anchor hitch knot. It’s a good idea to wear gloves to prevent rope burn. Experienced users report slowly dragging the magnet through the water provides the best results.

The Magnet

The Fisherman’s Magnet is specifically designed for use in the water, with a black enamel finish to help resist corrosion. This powerful fishing magnet lifts up to 150 lbs. and the eyebolt and nuts are included.

Magnetic Road Sweepers are the Right Tool for Emergency Access

TYMCO® utilizes Magnet Source® Sweepers for Road Clean-up after Fertilizer Plant Explosion in Texas.

There are so many factors involved with providing an effective response to an emergency situation. Having the right tools and equipment is always part of a successful solution.

TYMCO, Inc. is a manufacturer of Regenerative Air Street Sweepers located in Waco, Texas, about 19 miles south of West, Texas. When the fertilizer plant located in West exploded on April 17, 2013, TYMCO volunteered to bring their expertise, equipment and the needed sense of urgency to get the job done right and quickly.

“The situation was that emergency vehicles were having difficulty gaining access to the necessary areas because of all the debris scattered across the roads,” said Gary Young, Vice President, Engineering for TYMCO. “The first priority in our cleanup role was to clear the roads of all hazardous debris. We have a large selection of road cleanup equipment to handle any size task. We chose to go with the Magnet Source® 84” and 96” Hanging Magnetic Sweepers because of the need for speed and simplicity. We did not have time to install our larger electrically actuated magnetic sweepers, so we chose to hang these off our big International Trucks and go,” Young explained. (The Magnet Source® brand is a trademark of Master Magnetics, Inc.).

“Our initial process was to have three to four people walking along with our street sweeper trucks, tossing large-size debris into the street sweeper, and periodically clearing off magnetic sweeper. The magnetic sweeper protected our trucks’ tires so we could proceed with cleaning up the rest of the debris,” Young added.

Hanging Magnetic Sweepers are available in widths from 18” to 96” from Master Magnetics. The Magnet Source® sweeper product line also includes push-type and trailer-type magnetic sweepers. These sweepers are super-powered, permanent magnets for the removal of sharp iron objects from roads, parking areas, loading docks, runways and other important traffic areas. Hang-type magnetic sweepers greatly reduce the possibility of costly flat tires and injuries caused by nails, scrap iron particles, staples, etc. Two eyebolts are installed on each magnet for suspending from vehicles.

Simply hang a magnetic sweeper from your forklift or vehicle bumper and “sweep” all contaminated areas. The sweeper hangs approximately 2” to 4” off the ground, and maximum operating speed is 5 mph. To clear collected debris, wipe the face of the magnet with a glove or heavy shop towel. There are also magnetic sweeper models available with quick-release handles for the easiest removal of collected debris.

Magnets Clear Dirt Roads of Hazardous Metal Debris

Master Magnetics offers various magnetic sweepers to clear metal debris from different kinds of surfaces – factory aisles and walkways to patios and roadways. Depending on the application, our magnetic sweepers offer the perfect solution, and range in size from small hand-held to trailer-type.

We recently ran across an interesting story about large magnets being used to clear roads of metal debris in Lancaster County, Nebraska.

Printing Direct to Magnet Creates Profitable Opportunities

Keeping your wide format printers busy is a primary key to your success.

The ability to print direct to flexible magnetic sheeting opens up entire new channels of business that you may have been missing.

From vehicle signs for contractors, realtors and restaurant delivery vehicles, to P.O.P. retail signs, calendars and local sports team schedules, there are an endless amount of items that make printing on magnetic sheeting a very profitable segment of your business.

Some printers are reluctant to take advantage of these opportunities because they feel that the traditional  two-step process of printing on a substrate and laminating to the magnet, or printing on unmagnetized material and then magnetizing it, is too time consuming and not an efficient process. Printing direct to magnet avoids these extra steps, saving time and money.  With good quality magnetic sheeting, excellent high resolution printing results can be achieved with solvent, eco-solvent, UV and latex ink systems. For aqueous inks, you can get magnetic sheeting already laminated with a paper topcoat for one-step direct to magnet printing

A common reason cited by printers for resistance to printing on magnet is the concern for running magnetic material through their printer. One problem may be if the platen is metal, the smooth and even flow of the magnet being fed into the printer would be restricted. This is easily overcome by covering the platen with styrene, chip board, vinyl or duct tape, or anything to create an air gap between the metal platen and magnet.

Other issues, such as print head height adjustment, ink saturation, or other metal parts of the printer that the magnet will come in contact with, can be answered by your printer manufacturer and referring to the printer’s profiles. “Everything you run through a printer requires a unique set-up for optimal performance and quality, and magnet is no different,” said Ralph Terramagra, Mutoh Eastern Regional Sales Manager. “The platen and post heater on most Mutoh printers are made of aluminum so they will not cause a problem with the magnet. There is a steel piece across the back where the media feeds in that will need to be covered as explained earlier. Basically, if you keep the magnet from sticking to metal it is really not much different than printing on vinyl. That being said, remember it is much thicker so keep your head height in a higher position, and it is also heavier so your print feed will need to be adjusted,” explained Terramagra.
