The Features of Force Field Mathematical Model of Neodim Magnet in Drug Delivery Device

The features of magnetic technologies application in medical practice for targeted drug delivery to pathogenic zones and the peculiarities of designs of magnetic devices intended for this purpose are considered. The specificity of using permanent magnets in open magnetic systems of these devices are noted. It is shown that, under certain conditions, the use of highly coercive neodymium magnets is preferable. Mathematical models were compiled and analytical formulas were obtained to calculate force fields created by neodymium magnets, which ensure the movement of magnetic nanoparticles along the body vessels.
