The coordinated activity of a myriad of ion channels in a cell is a spectacular biological and physical phenomenon. Understanding mechanisms governing the ion channel gating and setting membrane potentials is key to developing targeted therapeutic strategies using non-contact magnetic stimulations. In this study, we demonstrate theoretically that ion channel activity can be controlled by a static gradient magnetic field. The analysis revealed that specific ion membrane channels can be turned off and on by remotely applying a high gradient magnetic field, thus modulating the cell membrane potentials. The suggested model and mechanisms provide a general framework for identifying possible hidden mechanisms of biomagnetic effects associated with modulation of ion channel activity by high gradient static magnetic fields.
