Question

Which of the following is true in context of Eddy currents?

• A. By Lenz's law, an eddy current creates a magnetic field that opposes the magnetic field that created it.
• B. Eddy currents are loops of electrical current induced within conductors by a changing magnetic field in the conductor, due to Faraday's law of induction
• C. Eddy currents are a cause of energy loss in alternating current (AC) inductors, transformers, electric motors and generators etc.
• D. All of the above

Answer 1

The correct option is D All of the above

Eddy currents are loops of electrical current induced within conductors by a changing magnetic field in the conductor, due to Faraday's law of induction,are a cause of energy loss in alternating current (AC) inductors, transformers, electric motors and generators etc.

By Lenz's law, an eddy current creates a magnetic field that opposes the magnetic field that created it.
