The following images depict the magnetic field distribution of the circular TMS coil at 9,10mm at 100%,80%,60% power of the Cadwell Stimulator.   Click here to download a sample of the sound of the coil when it is triggered. (The sound was measured at a distance of 5cm away from the coil, at 100% power.) Click here to see the colormaps.
