Abstract: For magnetic stimulation the desired electromagnetic field is produced by a magnetic coil to affect biological tissue and thereby to stimulate it for neurological diagnosis. The coil geometry determines the strength and the duration of the induced electric field in the volume of interest for a given stimulator: The aim of our work is to establish a relationship between the coil geometry and the strength as well as duration of the induced electric field. The calculated results show that there exists an optimal coil geometry for stimulating a given volume of the biological tissues. Our numerical calculation is restricted to an excitable tissue 15 mm below the lower plane of the coil.
