Correct option is D
· An induction furnace operates on the principle of electromagnetic induction, which is fundamentally the same principle used in transformers.
· In both transformers and induction furnaces, alternating current (AC) is used to create a varying magnetic field. Here’s how it works.
Induction Furnace Operation:
· The induction furnace consists of a coil through which AC flows, generating a magnetic field.
· This magnetic field induces eddy currents in the conductive material placed within the furnace.
· The induced currents generate heat due to the material’s electrical resistance, thereby heating and melting the material.
