Simple Experiment: Extraction of Energy from Permanent Magnets

In addition, why conservation of the momentum works, and conservation of energy - not?

The energy is still conserved, but only portion of it gets stored in macroscopic momentum of ballistic pendulum - the rest goes into increase of microscopic momentum of its molecules - and we call this momentum heat.

Its hard to see how it is conserved, considering that 95% simply disappears. But important part is, that it will be mistaken to apply a ballistic pendulum concept towards the jumping
EM coil for the recovering of its mechanical energy - it will be lost the same way as in a pendulum.
The better approach will be to catch the potential energy on the way down.

It doesn't matter, we are in overunity forum. The miraculous lost of energy bothers anyone here.

The RattleGen: This is a permanent magnet generator I developed a couple of years ago. OK, the thing works by adding kinetic energy but the way this is done is quite original. The electronic circuit is very elementary. I use a resistor to reduce the LED current. Doing experiments with a relay and a magnet, early 2013, I discovered on my oscilloscope screen a useful voltage. A ceramic magnet was put agains the relay coil. Pressing the contact lever made energy, as you can see in the video. A bit later I placed a strong neodymium magnet on the contact lever of the relay. As a result, the voltage was peaking 2 times higher on the screen. Then I took a small relay; the output peak voltage of the relay coil was 35 volt, without load. After the bridge rectifier the voltage peaks are smoothed by a condenser. To test the small generator I use an ultra bright LED. Take care; depending on the iron of the relay coil a stronger magnet will not give more flux, this because of the saturation. If you make the gap bigger between the contact lever and the relay coil the output will enhance. The magnet functions also as tension spring. The lever jumps back after pressing. This saves again one mechanical part. Before the LED light up you have to press the contactlever several times. The capacitor of 1000 microfarad 16 volt has to charge first. Watch the video to see the principle.

Very interesting, Bertoa. Video not playing here ("Error 10" in my third party player). Certainly more reliable than dynamo type flashlights with plastic gears. And a nice size.


BTW, you may try this: a low leakage capacitor, and instead of the LED with the resistor, you drive a joule thief+LED, that will use the power more economicly, and lites an LED down to maybe 0.5V cap voltage.
