TK device, TPU.. Only enter if you seek truth. Cause here it is...

Thats a good informative read.  I always enjoy your posts.  You have taught me a lot about electronics and electricity.  Thanks and hope you can keep up with the "long term" OU inventive spirit

Say we have two disc's.  that are nice uniform think magnets and you have a coil that runs in bettween them and you pulse that coil and when it comes out it drags more energy than it was originally.  TK's bag that looked like a lunch bag.  What was in it was all taped up, but it could be 2 large magnets with a coil in between them.

In one of TK's videos when he starts up his device you hear a very large coil vibrate.  It sounded like large degaussing magnet.  Does anyone else know what that sound is, if it's not a degaussing coil. 

This might be way out of left field, but what would happen if you used a degaussing coil in his setup??

The sound can be produced by two windings with two current slightly out of phase? As a transformer of a UPS powered by two current out of sync.........

What phenomenon exactly would produce the acoustic vibration if not magnetostriction nor Ampere forces, in the case you are describing ?

The sum of two sinewaves of the same frequency is one sinewave of the same frequency (or zero). This is true regardless of the phase difference between them.
Yet, the sound that ElementSix was asking about, clearly contains frequencies above 50Hz.

IMO only nonlinear phenomenon (such as ferro saturation) can increase the frequency of the input sinusoidal waveform (50Hz assumption).

Like SM TPU's vibration.....slight noise

no, loose windings...
