Model Loop Type -Demagnetizers

Work pieces must pass completely through the opening. Small work pieces should be passed through the area of strongest magnetic field. (This may be determined by the attraction of the work piece to these areas). When assemblies are to be demagnetized it may be advisable to dismantle the assembly and demagnetize each part separately.

Excessive heat will be induced into magnetic steel if it is allowed to remain in the demagnetizer. Conveyors whose side rails or bed are made of magnetic steel must be split and rejoined with non-magnetic materials such as stainless steel, aluminum, brass, etc. An alternative is to have only the belt pass through the demagnetizer. Another method is to place a Surface Type Demagnetizer under the belt and if necessary, another unit suspended over the belt so the work passes between the two Demagnetizers. These Demagnetizers should be placed on a non-metallic surface to reduce the heating caused by induction. Special stands are available.
