Induction furnace makes use of eddy currents.
Induction furnace has an alternating electric current-carrying coil surrounding the container. Eddy currents are induced into the coil such that these currents are circulated by producing high temperatures which are used for melting and making of the alloys.
Metals such as iron, steel, aluminium, copper are melted in the induction furnace. The working principle of the induction furnace is the induction heating.
