Proof of concept - perturbing a static magnetic field

@all

See electricity through a magnetic field in video. Watch 4:57 and 5:07 into the video.

Great find Chris. He has another video just showing the effect, repeated 16 times. He is applying 0.8 amps, 800 milliamps, current across the magnets at an AC voltage of 9 volts. Looks at the length of spark and the fact it is emited PERPENDICULAR to the length of the magnet.

I will report back with results within a day or two.

Bad news.  I finally completed my H-bridge and hooked it up to the coil.  It ran for about 3 seconds at 1KHz before self-destructing!

I am at a loss to explain why it did that.  The MOSFETs and driver chips were stone cold immediately after it stopped working.   Maybe diodes are needed to short out the back-EMF, but I am afraid that I might kill the effect that way.

Bottom line, it'll take me about a week to rebuild.  Sorry I couldn't get any actual testing in yet.

@eldarion
Could you please post a circuit diagram so we can help you ?
Many thanks.

What voltage did you have going to the coils ? Did you a resistor in series with coils to reduce the amps down, if so what value ? (When I get going I'll try larger value !!)

@ Eldarion,

Hi all,

If the magnetic field really gets as strong as the patent suggests then it doesn't seem surprising that there is an enormous power induced in the pulsing coils too!
I guess blocking diodes can be of help here..... problem being things like these are mostly left out of patent applications....
