General Information:
DC B-H Hysteresis Loop: Automatic measurement of the demagnetization curve of permanent magnetic materials such as ferrite, rubber & plastic magnet, AlNiCo, NdFeB, SmCo etc. Accurate measurement of the magnetic characteristic parameters: trace Br, coercive force HcB, intrinsic coercive force HcJ and maximum magnetic energy product (BH)max.
Conforms to international standard IEC 404-5.
Features:
- Automatic measurement on saturation hysteresis loop and magnetic characteristic parameters: Js, Br, HcB, HcJ, (BH)max of general permanent-magnet materials such as Ferrite, Rubber & Plastic Magnet and AlNiCo etc.
- Automatic measurement of demagnetization curve and magnetic characteristic parameters at 2nd quadrant: Br, HcB, HcJ, Hk (H90) and (BH)max of rare-earth permanent-magnet materials, such as NdFeB, SmCo etc.
- Acceptable sample shapes: toroid, round cake, square, tile and other irregular shapes.
- Adopt B-coil + fluxmeter to measure magnetic induction, zero shift of integrator can be auto-corrected through software.
- Adopt J-coil + fluxmeter to measure magnetical polarization, remnant coil area of J-coil can be automatically compensated through software.
- Use Hall magnetometer to measure magnetic field intensity, non-linear error of Hall probe can be achieved within ±0.2% for 0 ~ 2.4 T range via software.
- Adopt H-coil + fluxmeter to measure magnetic field intensity, Hall magnetometer used to indicate zero point of magnetic field to completely eliminate its nonlinear error.
- Automatically set the range of magnetic excitation voltage, fluxmeter and magnetometer.
- Complete magnetization, testing and demagnetization of general permanent magnetic from 20 seconds to 60 seconds.
- Perform saturation magnetization and testing of rare-earth permanent magnetic samples from 60 seconds to 120 seconds.
- Select state of demagnetization or magnetization of tested samples.
- Optional heater and temperature controller to detect magnetic characteristics of Ferrite, AlNiCo and rare-earth materials under high temperature (maximam 220°C).
- Select shoe jig for direct measurement on magnetic shoe.
