Demagnetizers

Demagnetizers Remove Unwanted Residiual Magnetism

Some materials retain residual magnetism if exposed to magnetic fields. The amount depends on the workpiece size and the type of material. To remove this undesirable residual magnetism, the object must be exposed to an alternating magnetic field, which eliminates the magnetism to the lowest possible value.

MPI offers two types of demagnetizers depending upon requirements. The handheld demagnetizer is ideal for large or complex components, such as molds, bearings, and various machine and mechanical parts, etc. It is an efficient tool where quick and mobile demagnetization is needed. The tabletop is best suited for quick and simple demagnetization of flat and small cylindrical components. It is easily integrated into a production line, for instance under a conveyor belt.

Magnetized workpieces cross the electrical plane, exposing the workpiece to an opposite magnetic field and creating an irregular magnetic field. By slow movement across the top plate and away, the unwanted residual magnetism is effectively removed from the object.
