Abstract: Magnetic particle imaging, uses magnetic fields of frequencies in the kilo-hertz range. Little research has been carried out upon effects on excitable tissue caused by time-varying magnetic fields in that frequency range. To learn about magnetic stimulation thresholds, a system that is capable of generating a very focused magnetic field strong enough to induce a muscular reaction was built. Stimulation thresholds at 7.38, 12.04, 16.5, and 25.27 {kHz} have been recorded in 31 trial participants. It has been proved that magnetic stimulation is possible up to even 25 {kHz}, and respective thresholds have been determined. This article presents the trial setup, procedure, and evaluation of field quantities.
