Vacuum induction melting

Vacuum induction melting ( VIM ) utilizes electric currents to melt metal within a vacuum . The first prototype was developed in 1920. One of the only ways to induce a current within a conductor is through electromagnetic induction . Electromagnetic induction induces eddy currents within conductors by changing the magnetic field . Eddy currents create heating effects to melt the metal.
