Background
The electromagnetic heating roller is a heating roller made according to the principle of heating metal by electromagnetic induction. When the magnetic flux passing through the closed loop changes, a current is generated in the loop, which is called an electromagnetic induction phenomenon. The current generated by the loop is called induced current. This current is generated in a closed loop of wires. If a metal object is placed in a magnetic field or cuts magnetic lines of force in the magnetic field, an induced current is generated inside the metal object, and the induced current is generally called eddy current (eddy current for short). Since the resistance of the metal is small, the eddy current is generally large, and thus the metal block heats up quickly. This phenomenon is commonly referred to as eddy current thermal effects.
