The working principle of bearing heaters

The working principle of bearing heaters 

The working principle of the bearing heater is to make the metal hot by eddy current in the alternating magnetic field. The principle is that thicker metal in an alternating magnetic field will produce an electric current due to the phenomenon of electromagnetic induction. When a thick metal generates an electric current, it forms a spiral path inside the metal, so that the heat generated by the current is absorbed by the metal itself, causing it to heat up quickly.
