The core used in transformer and other electromagnetic devices is laminated to
increase the magnetic field.
increase the level of magnetic saturation of the core.
reduce the residual magnetism in the core.
reduce eddy current.
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.
