ABSTRACT:
A magnetic variable resistor has an elongated band of electrically resistive magnetic material, with the side edges tapered to a sharp point so that the skin effect causes current to migrate to the edges to create greater resistance. A layer of insulating material can cover the band as it is coiled. Leads are secured to opposite ends of the band. An alternate form of the invention embeds the coiled band in a magnetic insulating material. Surface mount leads are flush with at least one surface of the insulating material.
