Glossary of Motor Terms
Coercive force, coercive intensity
Coercive force (or intensity) is a measure of the ability of a ferromagnetic material to withstand an external magnetic field without becoming demagnetized. This is defined as the intersect of the demagnetization curve with the horizontal axis in the second quadrature of the B/H graph as shown in the figure below. Coercive force is designated by HC, and its (SI) unit is Am-1 while the cgs unit is Oe (oersted).
1 Oe ≒ 80 Am-1.
