HOW INDUCTION HEATING WORKS
How exactly does induction heating work? It helps to have a basic
understanding of the principles of electricity. When an alternating
electrical current is applied to the primary of a transformer, an
alternating magnetic field is created. According to Faraday's Law, if the
secondary of the transformer is located within the magnetic field, an
electric current will be induced.

In a basic induction heating setup, a solid state RF power supply sends an
AC current through a copper coil, and the part to be heated is placed inside
the coil. The coil serves as the transformer primary and the part to be
heated becomes a short circuit secondary. When a metal part is placed within
the induction coil and enters the magnetic field, circulating eddy currents
are induced within the part. , these eddty currents flow against the
electrical resistivity of the metal, generating precise and localized heat
without any direct contact between the part and the coil.
