Magnetic therapy out of camera flash.... n1 can comment?

The easy way would be to buy a cheap, disposable camera, with a flash, take out the flash driver (inverter, HV cap, Xenon tube etc..) and simply cut one wire going to the Xenon tube, and insert a large handwound coil (air core). Most seem to wind it around the spool of a VHS tape, making it 2" by 1". Alternatively, buy a Xenon strobe, and use that. Either way, the Xenon tube is used as a high-current switch, since we're discharging a 400uF cap at 330-400V in about 10us

I tried this but the magnetic field created was quite small (compass nidlebarely movig about 5-10 cm away)

Back around 1900 when electricity and ultraviolet radiation became well known there were all sorts of patent medical treatments using them. The reason this is not used today is that it does not work, not because it is a new idea.
