I can answer you responsibly. I tested it myself and it’s true!
The principle of this device is radio wave induction (the same principle is used in current wireless charging). The invisible electromagnetic waves in the air cause the coil to obtain alternating current induced electromotive force through electromagnetic induction. it is not a true perpetual motion machine. In the absence of electromagnetic waves, it doesn't work as far as signals are concerned (what we call electromagnetic pollution is actually various electromagnetic waves in the air, which are also a form of energy, but it is the source of this type of static magnetic energy generation)
It's as if the mineral radio I made when I was a kid didn't have an energy supply for it. 'entire electronic device, but it was still possible to listen to the radio normally OneOne of the key components was the magnetic rod wrapped with a coil.
There was also the previous transformer. When disassembled, there are two physically isolated coils. One coil passes alternating current and the other. generates different alternating voltages according to different turns. It is also based on the principle of electromagnetic induction.
This type of static electromagnetic power generation device If placed in a sealed large iron box, it will fail, because in this In this case, external parasites will be protected. If there are no external induced waves, which we often call electromagnetic pollution, to provide the initial energy, the static magnetic coil will also generate energy. It will not produce electricity.
The little reel in the video looks a little unreliable, but the principle is still correct. If you want to get better results, you need more tbear and of greater volume. I directly disassembled a used ceiling fan and experimented successfully. the big coil inside
You can try it yourself or find materials from used motors and used fans ready to use. There is trash in our community. Shopping stations, look for things that are very cheap. /p>
Siemens discovered through research and experiments that electricity can also be generated using electromagnets instead of permanent magnets in generators. Indeed, the iron core of the electromagnet always retains weak magnetism when no current is flowing. When the coil rotates, this small residual magnetism can be used to generate electric current. Current is returned to the electromagnet, causing its magnetic force to increase. As a result, the electromagnet can produce strong magnetism and thus emita strong current.
