MHT CET · Physics · Alternating Current
The core used in transformer and other electromagnetic devices is laminated to
- A increase the magnetic field.
- B increase the level of magnetic saturation of the core.
- C reduce the residual magnetism in the core.
- D reduce eddy current.
Answer & Solution
Correct Answer
(D) reduce eddy current.
Step-by-step Solution
Detailed explanation
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.
2. The transformer's core is laminated to reduce eddy current and improve efficiency.
