This is a further refinement of the Magnetic Pulser developed by Robb incorporating Bryan's short wire experiment with additional safety features for handling the higher currents. This not a beginner project. Also caution is advised as Bryan experienced severe herx reactions using this much higher power device. This version uses a Velleman pulse width modulator board driving an automotive starter solenoid relay driving the coil at 300 amps from a 12 volt battery. The theory of this pulser is that the healing effect is a result of the arcing of the relay contacts producing a wide frequency plasma. The design of the UHF and HF coils is to enhance certain frequencies and radiate them into the body.
