    When a ferromagnetic material is taken through a hysteresis cycle, the magnetic susceptibility cannot be:

    A) Zero

    B) Infinity

    C) Negative

    D) Constant

    Correct Answer: D

    Solution :

    Magnetic susceptibility is the slope of I-H curve.
    Slope of I-H curve for ferro may be positive, negative and zero so never be constant.
