Demagnetization theory Coil Type magnetizer is a kind of alternating current air core coil, When magnetizing current field is generated inside the air core. If you put in and out the magnetized work into the magnetic field, the regular magnetic aligned work is vibrated and magnetic domain becomes differential direction then the work is demagnetized. Widely used in machine building, bearings, hydraulic parts, stamping parts, hardware products tools, mold manufacturing industry needs demagnetization. ONE.Principle: coil through the Constant current ,so that the workpiece through and away from the coil (General use conveyor belt), then workpiece will lose magnetism.Larger power consumption, when working at long hours and the coil will heat.Use for with long strip and large of the workpiece. Widely used in machinery, bearings, hydraulic parts, stamping parts, hardware products, mold manufacturing and other need needs demagnetization industry. TWO.Parameters: Notice: Other specifications of size and special requirements can be customized.
