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
