This 220-volt demagnetizer which is made of iron and is silver in colour. Demagnetizer effectively removes surface residual magnetism from high speed steel, chrome, spearing steel or die steel. As the magnetic poles contact the object to be demagnetized, the magnetism is released. Thick objects may be demagnetized by applying both ends to the demagnetizer. This demagnetizers is supplied with on/off switch. Demagnetizers utilize 220 v single phase alternatives electrical current.
