The particles of the paramagnetic nanometers-iron nuclide targeting therapy system, utilizing guided by the revolving magnetic field, was studied theoretically using MATHCAD simulations. This research used a new "magnetic drug" which was the paramagnetic nanometer-iron nuclide (PNIN) for treatment tumor, when it was injected into the blood vessel, revolving magnetic guided PNIN through the circulatory system to retain them at a target site. First, general mathematical expression of magnetic forces is presented according to theory of electromagnetic fields. Then, based on the symmetry of magnet...
