AC magnetic susceptibility measures magnetic moment of a sample which is exposed to an oscillating external magnetic field.
Two coil sets are used to measure the AC magnetic susceptibility, one to apply the oscillating magnetic field (primary or excitation coil) and the other to measure the induced voltage (secondary or pick-up (sensing) coil). The induced voltage is proportional to the change of the time varying magnetic moment (Faraday’s law) and the AC magnetic field frequency and amplitude (typically 1 Hz ~ 1 kHz and 0.1 ~ 10 Oe). The AC magnetic susceptibility can be used as a complimentary method to DC magnetic measurement techniques and also to study magnetic relaxation.
