This is a multi faceted answer.
On this forum, one is spinning magnets to generate more 'electrical" output than electrical input with the Multi-meter being the proof generally.
But spinning magnets generate magnetic Fields and Man doesn't utilize Magnetic Fields. He's always looking for a greater amount of electrons. So the majority of Field Energy is used in heat and most loss is in eddy currents. You guys need our propriety Magnetic Shielding Technology and so to does NASA to get anywhere beyond near earth orbit. My Adams Pulsed Motor used both sides of each magnet and spin at 1000 rpm. with a 2 foot diameter wheel.Some where I have it on sony cassette video as it was shown at a Nexus conference in the 90's. I've moved on. Joecells are an upgrade to using Spinning Magnetic Energy at distance WITH WIRES to using Fields in situ.
Outside our personal experimental labs, Spinning magnets Is the 'generator' of Tesla. and we know lots of ways to utilize it.
One has 6 senses working in varying degrees of effectiveness. You can sense the Field by eyeing the results, you can Hear and Feel the Global Field Vibrating. Some sense or see the "fire" of the Field. Instruments will pick up the Field of the wiring in your house. Smell is usually ozone as the Magnetic Field energizes the oxygen frequencies and this we call O3
Plug into the wall an old school wall wart. The heavy kind Not switching or voltage detecting. Gather all your permanent magnets up. Hold each one close to the Wall Wart and Feel the difference in each Vibration of each magnet makes to the same source.DO NOT TOUCH the Wall Wart you WILL get electrocuted.Which is not a good way to utilized this energy. And is totally UN-explainable with 'electrons'. To prove this make sure your partner knows Resuscitation science.
If one could use a sensitive vibration meter, one could detect the Different Field Frequency of each magnet as no two magnets will have the same vibration. So spinning magnets in an overunity motor will have the most unusual eddy currents with all them different frequencies being generated. Unless you have magnetic shielding.
This Experiment could be repeated for each "source" of Mains Power. like countries with 50 or 60 cycles. Or solar or wind from 48VDC to 120 VAC for example..
Field Science has totally made spinning magnets obsolete in areas of Water Purification, Desalination, Plant Fertilizers, Oil Production
The Aqua Chi uses Spinning Magnet Energy, Its FIELD Generated is best Utilized in anti Ageing and Longevity. https://www.youtube.com/watch?v=a5lzb0AXmAE https://www.youtube.com/watch?v=a5lzb0AXmAE
And if you are sick or have STD Warts or cancer or vaccine autism or PMT or Eczema or Golden Staph , you pretty much SENSE it real Quick.
Some can feel the Field pulsing from 10 feet away. It Pulses at 50 or 60 cycles per sec and if we made it 113VAC, its effectiveness in this area would greatly increase.
The short answer is... everything is a Magnetic Field and by generating Magnetic Fields one can interact with all matter any way one wishes. Tesla brought us the Coil and the millions of coil variations allow us to use it millions of ways. Sticking it in water for healing or OIL production or Desalination he never thought of. Your senses will detect this.
The Fisher and Paykel washing machine motor is a Low Drag motor so easily makes with minimal input.
