An automatic none destructive apparatus for measuring the magnetic permeability of cylinder ferrimagnetic sample is introduced. Based on Faraday’s law and demagnetizing factor iteration formula, the device consists solenoid, induction coils, Lock-in amplifier 7265 and a computer for controlling the applied magnetic field and permeability calculation. Five high-resistivity iron alloy rod are chosen as samples and typical material permeability is compared with previous work.
