remanencesaturation field intensitymagnetic

The Magnetically Hard Materials Measuring System is a permanent-magnet testing platform designed to measure magnetic performance parameters and to produce BH hysteresis loops and demagnetization curves for a wide range of permanent magnet materials.

Materials covered:

• Rare earth permanent magnet materials (e.g. NdFeB)
• Metal permanent magnet materials (e.g. AlNiCo, FeCrCo)
• Ferrite permanent magnet materials (e.g. barium ferrite, strontium ferrite)
• Other permanent magnet types (micro powder magnets, nano magnets, plastic magnets, machinable magnets)

Measured magnetic performance:

• Saturation magnetization field strength (Hmax)
• Remanence (Br)
• Coercive force (Hcb)
• Intrinsic coercive force (Hcj)
• Maximum energy product ((BH)max)
• Recovery permeability (μrec)
• Hysteresis loop and demagnetization curve
