Lenz's Law, Eddy Currents & Induced Electric Field

Two conducting wire loops are concentric and lie in the same plane. The current in the outer loop is clockwise and increasing with time. The induced current in the inner loop is

Show answer and solution

Answer: (b)

  1. Clockwise current in the outer loop gives an inward (into the plane) field inside it.
  2. This inward flux through the inner loop increases with time.
  3. The induced current must give an outward field, so it is anticlockwise.
  4. So the answer is (b) anticlockwise.
