The core used in transformer and other electromagnetic devices is laminated to

Options

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

Correct answer

D. reduce eddy current.

Step-by-step solution

1. According to Faraday's law of induction, eddy currents are loops of electrical current induced within conductors by a changing magnetic field. 2. The transformer's core is laminated to reduce eddy current and improve efficiency.
