| Abstract: | A magnetic agglomeration force formula applicable to magnetic agglomeration process of two ferromagnetic particles in (or out of) magnetic field is derived on the basis of magnetic medium surface current and electromagnetic theory. By the change of its form, this formula can be transformed into the magnetic force formula in traditional magnetic separation theory, which attests its applicability. The derived formula, with simple form and clear physical concept, can characterize the magnetic agglomeration force of two particles with different diameters and in any distance. It is prolific of magnetic agglomeration theory. |
