Lenz's Law, Eddy Currents & Induced Electric Field

A bar magnet falls from a height through a metal pipe. Its acceleration will be (gg = acceleration due to gravity)

Show answer and solution

Answer: (a)

  1. The falling magnet changes the flux through the metal pipe, inducing eddy currents.
  2. By Lenz's law these currents oppose the motion, giving an upward force.
  3. Net downward force <mg< mg, so acceleration is less than gg. Answer (a).
