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.

There is, however, no magnetic charge. The "elementary unit of magnetism" is the magnetic moment, also called the magnetic dipole. It is more complicated than charge because it is a vector, meaning it has both magnitude and direction. We will ask ourselves two basic questions: 1. What sort of magnetic fields does a magnetic moment create? 2.
