    The core used in transformer and other electromagnetic     instruments     is laminated, the reason is :

    A) to increase the electric field

    B) to increase the magnetic field

    C) (c) to reduce the loss of energy due to eddy currents

    D) to decrease the resistance

    Correct Answer: C

    Solution :

    The core used in transformer and other electro-magnetic instruments is laminated, so that the resistance is increased. Due to this increase, energy loss due to eddy current is reduced.
