Pull test kits
January 10, 2012
Designed to test the strength of a magnet to determine how effective it will be in its given application, IMI magnetic pull test kits can be used as part of a regular quality control program or to compare 2 magnetic devices that look very similar on the outside, but may have different magnetic circuitry or magnet material on the inside. Magnetic pull strength testing can be performed on magnets with round or flat surfaces and on permanent or electromagnetic circuits. Pull strength is determined by using a calibrated scale and a ferrous test piece. The pull strength, or pounds of pull it takes to release the test piece from the magnet, indicates the strength of the magnet.
