Question:
Induction Furnace is based on application of which of the following?
Options:
Coulomb's Law
Eddy Currents
Hysteresis
AC Generator
Correct Answer:
Eddy Currents
Explanation:
Induction furnace can be used to produce high temperatures and can be utilised to prepare alloys, by melting the constituent metals. A high frequency alternating current is passed through a coil which surrounds the metals to be melted. The eddy currents generated in the metals produce high temperatures sufficient to melt it.
