Induction furnace uses ..... to produce heat.
Options
- Aeddy current
- Bresistance
- Ccapacitor
- DNone of these
Correct answer
A. eddy current
Step-by-step solution
In induction furnace, a metal specimen is placed in a rapidly changing magnetic field, therefore a large eddy currents are set up in the metal specimen. Due to large eddy current, heat produced in the metal specimen is sufficent to melt the metal. i.e, metals are extracted from their ores in the induction furnace.
