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 emit a strong current.
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 electromotive force induced by alternating current through induction.electromagnetic. 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. The whole electronic device, but it was still possible to listen to the radio normally. One 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 of the coils is connected to alternating current and the other. another coil generates different alternating voltages depending on the different number of turns. It is also basedon 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 case, the clutter external will be protected. If there are no external induced waves, what we often call electromagnetic pollution, to provide the initial energy, the static magnetic coil will not generate energy either. electricity
The little coil in the video looks a little unreliable, but the principle is still correct. If you want to get better results you need more rounds and larger volume, I directly took apart a waste ceiling. fan and successfully experimented with the large 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, searchhez these things. which are very cheap
