Question
What are eddy currents? Write any two applications of eddy currents.

Answer

When a bulk piece of conductor is subjected to changing magnetic flux, the induced currents, developed in it is called Eddy current.
uses:

  • Electromagnetic damping.
  • Induction furnaces.
  • Electric power meter.
  • Induction therapy.
  • To find the melting point of precious metals.
  • In speedometer of vehicles.
