Claim Text:
1. A magnetic stimulation system for inducing approximately rectangular electric field pulses in a body organ, comprising: a charging device charging a first electrical energy storage device to an independently selectable first positive voltage (Vc1) and a second electrical energy storage device to an independently selectable second positive voltage (Vc2) whose magnitude is independent of the first positive voltage; an operator-controlled device configured to independently select said first and second positive voltages Vc1 and Vc2; a stimulating coil; a first and a second switching device electrically coupling said first electrical energy storage device to the stimulating coil to produce current pulses with a positive rate of change in the stimulating coil; and a third and a fourth switching device electrically coupling said second electrical energy storage device to said stimulating coil to produce current pulses with a negative rate of change in the stimulating coil, wherein the stimulating coil is configured to produce, in response to a combination of the current pulses with the positive and negative rates of change, magnetic field pulses that induce predominantly unipolar and approximately rectangular, 20-50 microsecond duration electric filed pulses in the body organ.
