    When a sheet of iron is placed in between the two co-axial coils, then the mutual inductance between the coils will:

    A) increase 

    B) decrease

    C) remains same                

    D) cannot be predicted

    Correct Answer: A

    Solution :

    (a) increase We know that the mutual inductance depends (directly proportional) on the permeability of the medium surrounding the coils. When the permeability of the medium is increased by inserting a sheet of iron, then the mutual inductance between the coils also increases.
