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.
