A comprehensive overview of magnet testing & standards including MDFA pull test standards, MMPA magnet guidelines, tips for shipping magnets & more. Home About Us

Pull test results can help determine if (or when) a magnet needs replacing. Magnets with visible cracks or wear holes should be removed from operation immediately, regardless of test results.

Jan 30, 2025 · Standard Test Method for Magnetic Properties of High-Coercivity Permanent Magnet Materials Using Hysteresigraphs. 4.1 This test method is suitable for magnet specification, acceptance, service evaluation, quality control in magnet production, research and development, and design.

MPI’s magnetic pull test kit is the most accurate and easiest method to test the strength of your magnets. This easy-to-use, compact gauge fits into tight areas and is battery-operated (four AA batteries included.).

One way to test the strength of a magnet is by seeing how many paperclips or other small metal objects it can hold. Start by laying the magnet flat on a table or other surface. Then, slowly add paperclips or other small metal objects to the top of the magnet.

Eriez has developed kits that when properly used will help you monitor the efficiency of your separator by measuring the holding force of a magnet.

With access to a wide range of tools & specialized instrumentation, Arnold Magnetics' engineering team will test your magnetic systems performance including permanent magnet testing, magnetic field mapping, & magnetic properties at high & low temperatures.

Aug 1, 2012 · Know The Proper Steps To Test For Magnetic Strength. Most industrial magnet manufacturers have adopted standard test equipment that measures the holding force of a magnet. Periodic testing of magnets helps determine whether a magnet needs to be repaired, upgraded or replaced.

convenient way to test permanent magnet materials. Other values such as operating flux density (B d), operating field strength (H d), coercive force (H. residual flux density (B r), and maximum energy product (BH max) can be derived from the measured moment value.

The MagNet Test Facility at CERN (SM18) (Image: CERN) The MagNet test facility is based at CERN in Geneva, Switzerland offers testing on superconducting magnets and devices refrigerated at low temperatures and high currents.
