Product Features:

Automatically performs demagnetization of closed-circuit samples using AC low-frequency demagnetization at frequencies not exceeding 10Hz, ensuring repeatability of initial permeability for metal soft magnetic materials.
Uses the impact method to test the basic magnetization curve and permeability curve of closed-circuit soft magnetic material samples.
Uses the impact method to test the static hysteresis loop and related parameters of soft magnetic materials.
Allows scanning method in open-circuit solenoids and Epstein frames.
