    The core of a transformer is laminated to

    A)  increase the magnetic flux linked

    B)  reduce the power loss due to eddy current

    C)  reduce the flux leakage loss

    D)  reduce copper loss

    E)  reduce hysteresis loss          

    Correct Answer: B

    Solution :

                    Eddy currents are set up in the iron core of the transformer  and  generate   heat,  with consequent loss of energy. To minimise these losses the iron core is laminated by making, it of a number of thin sheets of iron, insulated from each other.
