Abstract
A device for measuring alternating current (AC) magnetic susceptibility and the method for measuring the same are provided. The device comprises an AC magnetic susceptibility coil set, a signal capturing unit, and a signal processing unit. The device detects AC magnetic susceptibility signals from under testing particles in the magnetic field with variable AC frequencies, and extracts the AC magnetic susceptibility intensity variation and phase difference and/or the real part and the imaginary part of the AC magnetic susceptibility by the signal processing unit.
