Question

State one use of eddy current

Answer 1

Answer:

The minor application areas where eddy currents are utilized include use in energy meters, automobile speedometers, induction alternating current (AC) motors, free-fall devices, as a way of detecting coins in vending machines, to increase temperatures uniformly in induction furnaces, and in proximity/displacement.

Answer 2

Answer:

Eddy currents cause the rotation of shiny metal discs in the electric power meter. Electric currents are induced in the disc by magnetic fields produced by alternating varying currents in a coil. -Induction furnace: Induction furnace is used to prepare alloys and produce high temperature
