.... In practice, however, residual magnetization is rarely used because use of an applied magnetizing field ensures that the material is in the required magnetic state and because applied fields provide more flexibility. (It is possible to produce high or low flux density.) Control of the strength...

...., carbon steels). The μ r and χ m of ferromagnetic materials depend significantly on magnetic field strength at any temperature below the Curie point . Ferromagnetism is explained by the concept that some species of atoms possess a magnetic moment—that is, each atom behaves like an elementary...

... they, in turn, require simple coil geometries. Electromagnetic energy is more easily coupled into the part due to closer proximity to the workpiece and the generation of a more uniform magnetic field. Uniformity, as well as field strength, improves as the number of turns in the coil is increased. A larger coil...
