You can choose to move either the magnet or the conducting loop.

Learning goals

  • To illustrate a simple and historic experiment performed by Faraday in 1831 to study the laws of induction.
  • To emphasize that whether it is the magnet or the conducting loop that turns or moves, the effect is the same.
  • To introduce the problem of relativity that was resolved by Einstein 80 years later.
