Magnetic field goes through the metal of the induction coil, then generate vortex flow(vortex flow: also called Foucault currents. With the electric magnetic induction, current is generated from the inner conductor, much energy is generated by AC magnetic field changes) make metal rise in temperature rapidly and melt. The flow of the HF furnace’s large HF current is coiled to heating coils as circularity or other shapes. ( usually made of copper pipe )
So the polavity of the magnetic mount of the beam changes by the coils. Putting metal which is heated inside coils, flux would go through the whole heated metal, the opposite direction among the heated metal and heating current would come into being very large eddy current. As resistance is existed among heated metal, so much energy is brought about, then heated metal rises its temperature quickly. The heating processing is achieved finally.
