Plz also explain me in detail what Eddy currents actually are and how are they formed??plz

Expert Answer:

  • Eddy currents are defined as current induced in a thick conductor when the conductor is placed in a changing magnetic field.
  • It is a current induced in conductors which oppose the change in flux that generates them.
  • The tendency of a changing magnetic field is to induce a current that opposes the change.
  • These currents flow in closed loops within conductors, in planes perpendicular to the magnetic field.
  • However, the formation of these eddy currents depends on the shape of each conductor 
  • Eddy currents are undesirable since they heat up the conductor and dissipate electrical energy in the form of heat.
