  • Purpose: Illustrate that a changing magnetic flux induces an emf.
  • Use a B-field indicator, or compass, to show direction of B-field around magnet; connect coil of wire to galvanometer and move coil in and out of B-field to deflect galvanometer needle.
  • Location: magnet and coil located in L01; galvanometers are in L35, shelf F3, in plastic bin.
