In its most general form, magnetism may be defined as a special type of the physical interactions that arise between moving electrically charged particles. The transfer of magnetic interaction, which forms a bond between spatially separated bodies, is accomplished by a special material carrier, the magnetic field.
In classical electromagnetism, magnetization (magnetisation in British English) or magnetic polarization is the vector field that expresses the density of permanent or induced magnetic dipole moments in a magnetic material.
