Thanks again to Orthofield for sharing!
Homopolar Generator as I understand it:
Bell's patent is based on the same principle as Faraday's Homopolar Generator.
Bell's patent also gives a structure: the magnet rotates and the copper tube is fixed, so that the brushes or mercury pools of Faraday Homopolar Generator are not required, and the frictionless and no spark stable direct drawn current.
Similarly, the copper disc of a Faraday Homopolar Generator can be fixed, only rotating the magnet, and a steady current can also be drawn.
But there are important differences: in Faraday Homopolar Generator, a part of the sector near the copper disc connection lead wire is the effective power generation part, and the rest of the copper disc provides almost no current to the brushes. Bell's patent, the longer the fixed copper tube, the more efficient it is to use most of the cross-section of the copper tube.
The power generation principle of Homopolar Generator, is the most basic: wire cutting magnetic field line principle.
The most important characteristic of Homopolar Generator is that there is "no Lenzi Effect".
Homopolar Generator with brushes can be simplified to a situation where only one copper wire generates electricity: the secondary magnetic field generated by the output current is perpendicular to the magnetic field of the rotating magnet, and the Lenzi effect does not affect the rotation of the magnetic field.
There are articles that say that the COP=5 of Homopolar Generator.
Some articles say that Homopolar Generator can OU without the Lenzi effect, but the experimental results do not clarify the experimental device OU.
Homopolar Generator are not OU devices. because, although Homopolar Generator do not have the Lenzi effect, the rotating magnetic field during power generation needs to provide a Lorentz force to drive the offset of electrons. The more electrons are offset, i.e. the greater the output current, the greater the Lorentz force required.
Reducing the Lenzi effect, it is possible to OU, probably from the transformer principle.
Seniors introduced an asymmetric transformer:
Figure 1
Many people experiment, it is true that there is no Lenzi effect, but there is no output either.
Can the Lenzi effect-free of Homopolar Generator be used in transformers?
Can the alternating magnetic field generated by the primary coil of the transformer be equivalent to the secondary coil cutting the magnetic field lines?
If yes, this is the key.
We wrap the secondary coil vertically around the place where the magnetic field lines of the secondary magnetic field are concentrated like a Homopolar Generator:
Figure 2
Is it possible to OU?
This is only a schematic diagram and cannot be applied in practice.
Is it not possible to wind a suitable secondary coil in practice?
Thank you
