The core used in transformers are laminated to

Options

  1. Aincrease the magnetic field.
  2. Bincrease the level of the magnetic saturation of the core.
  3. Creduce the residual magnetism in the core.
  4. Dreduce eddy current losses in the core.

Correct answer

D. reduce eddy current losses in the core.

Step-by-step solution

There are many causes due to which energy is lost in transformer. Eddy current is one of them. So as to minimize the lost heat by eddy currents, the core of transformer is laminated.
