    The following images depict the magnetic field distribution of the figure-8 TMS coil at 9,10,10.5 mm 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.)
