Eddy Currents

  • Circulating currents called eddy currents are induced in bulk pieces of metal moving through a magnetic field.
  • The eddy currents are in opposite directions as the plate enters or leaves the field.
  • Eddy currents are often undesirable because they represent a transformation of mechanical energy into internal energy.
  • Section 31.6

Eddy Currents, Example

  • The magnetic field is directed into the page.
  • The induced eddy current is counterclockwise as the plate enters the field.
  • It is opposite when the plate leaves the field.
  • The induced eddy currents produce a magnetic retarding force and the swinging plate eventually comes to rest.
  • Section 31.6

Eddy Currents, Final

  • To reduce energy loses by the eddy currents, the conducting parts can.
    • Be built up in thin layers separated by a nonconducting material
    • Have slots cut in the conducting plate
  • Both prevent large current loops and increase the efficiency of the device.
  • Section 31.6
