Difference Between Dia Para and Ferromagnetic Materials

Apr 06, · When this type of materials is attracted to an external magnetic field, they get induced magnetically and can behave as tiny magnets. In industrial scale, ferromagnetic materials are separated from other materials using low-intensity magnetic separators that use a magnetic field with 0.04 Tesla.
