Abstract
This invention is concerned with a portable demagnetizer which includes a demagnetizing head supported within a hand held housing. Also contained within the housing is a variable control for applying voltages of decreasing step-less magnitude to the demagnetizing head; and means are also provided to apply a step-less alternating current power to the demagnetization head while voltages of decreasing magnitude are applied to the demagnetizing head. The housing is provided with a control means on the outside thereof so that the demagnetizer may be hand held and varied at the same time by a single individual user, particularly because of a minimum of parts and the use of step-less decreasing voltage magnitudes and the use of step-less alternating current power, which is applied to the demagnetizing head. Similar results can be achieved by slowly moving the work away from the alternating field.
