Nowadays we achieve good results with classical electroporation in various fields of use from electrochemotherapy, gene transfer to pasteurization of food and electrofusion. Due to exposure of the cell to the electric field, changes in the cell membrane begin to occur. These changes, under certain conditions, allow transition to ions and molecules, which is in normal circumstances prevented. As an alternative to electroporation with a pulsed electric field, the idea of permeabilizing the cell membrane using an alternating magnetic field has recently been raised. This method has not yet been fully explored, but it is very useful especially in cases where access to ordinary electrodes is disabled or too dangerous. In my master's thesis, I found the best figure-8 coil through numerical modelling among the selected constrains, with which we could create an induced electric field. Figure-8 coil offers us a better localization of stimulation area, but the depth of reach remains questionable. It is difficult to decide which coil is generally the best, since some have proved to be better at the strength of the electric field, the other at the density of magnetic flux and third at a greater depth of reach. In the middle of the coil the electric field strength of 101.76 V/m and a magnetic field density of 855.49 mT is reached. We are satisfied with those results, but with better input parameters, the results could be further improved.
