driver for Helmholtz coils
driver for Helmholtz coils
(OP)
I am trying to design a driver for a Helmholtz coil pair which is for a medical device (magnetic stimulation). The coils are 30cms diameter and the space between them is 50cms. The specification requires 75 turns on each coil and the power output is 0.5mT. The circuit is pulsed at 50Hz with a 1 second interrupt. Can anyone tell me a good circuit diagram for a driver for this device? Any help is greatly appreciated.

Have you calculated how much electrical current you require?

This would allow the fastest rise time into the coil [up to 150 VDC across the coil] and the amplitude of the pulse sets the current into the coil.
