Transcranial magnetic stimulation (TMS) can be used to excite the human cortex noninvasively as well as activates scalp muscles and sensory receptors. Since the field of the old traditional coils drops off quickly as it goes into the brain, a deep brain stimulation overstimulates the surface which is not only painful but also causes more effects on the outer part of the brain with little inside stimulation. This paper presents a Magneto Quasi-Static (Biot-Savart) approximation, used with the assistance of a low-frequency solver, to simulate the TMS application and finds the electric and magnetic fields distribution on an anatomical human head model due to the exposure from the applied pulse signal, of 10000 A peak and 280 µs width, through different coil forms. A well-known traditional coil was examined as well as a novel coil form was suggested and simulated to examine deep brain stimulation.
