Eddy current:

  • Eddy currents are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday’s law of induction.

EXPLANATION:

  • Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, through heat generated in the object by eddy currents.
  • So we can say that the heat is generated in the induction furnace by eddy current. Hence, option 1 is correct.
