Abstract

This is a technique for determining the varying polarity phase of magnetic fields in physically confined locations by providing a tiny probe to transfer the field under test to less confined areas where proper analysis is possible. A highly permeable magnetic ribbon 1 serves as the tiny probe and is inserted into the confined field produced by coil 2. The ribbon is then connected to a gaussmeter by appropriate circuitry. The device may be used to test winding polarity on each track of a magnetic tape head.
