In the macroscopic formulation of electromagnetism, there appears two different kinds of magnetic field: • the magnetizing field H which is generated around electric currents and displacement currents, and also emanates from the poles of magnets. The SI units of H are amperes/meter. • the magnetic flux density B which acts back on the electrical domain, by curving the motion of charges and cau… WebCorresponding Author. S. A.
