Lenz's Law, Eddy Currents & Induced Electric Field

Eddy currents are produced when

Show answer and solution

Answer: (d)

  1. Eddy currents need a changing magnetic flux through a bulk conductor.
  2. A steady field or steady current gives no flux change, so (a), (b), (c) give no eddy currents.
  3. A thick metal plate in a varying field has changing flux. Answer (d).
