Principle

A metal disc rotates on a bearing-mounted shaft in the presence to two out-of-phase alternating magnetic fields. Eddy currents are induced in the disc and forces are imparted onto this current-carrying conductor. Out-of-phase alternating fields also cause the rotational movement in an AC electricity meter.

Benefits

  • Demonstrative experiment due to large instruments
  • Easy and sturdy setup
