In magnetic particle testing, we are concerned only with ferromagnetic materials. 3.2.2.4 Circular Magnetic Field. A circular magnetic field is a magnetic field surrounding the flow of the electric current. For magnetic particle testing, this refers to current flow in a central conductor or the part itself. 3.2.2.5 Longitudinal Magnetic Field.
Figure 1: In a record head, magnetic flux flows through low-reluctance pathway in the tape's magnetic coating layer. Magnetic tape Magnetic tape used for audio recording consists of a plastic ribbon onto which a layer of magnetic material is glued. The magnetic coating consists most commonly of a layer of finely ground iron
