A motor design to defy Lenz' law?

  • #1
motor design.png

1. The two rotors (purple, green) are electricaly isolated but mechanically fit to rotate along same axis
2. The motor action on the left side rotor will move the armature set, this will produce currents in right side rotor that will pass via a variable load.
3. do you see the magnetic feilds of both rotors cancelling each other especially when the no. of turns are large
4. will this cancel lenz effect on generator side or both sides?

You have a motor-generator pair and it does not even transform the voltage. Any time you cut magnetic flux with a conductor connected to a load such as the right side of your drawing you will have an opposing force on said conductor. In other words, it gets harder to push the conductor through. A heads up: Discussion of things of this nature are prohibited on PF. Thought I would explain why your scheme won't work though.

it is difficult to move rotor of generator because the magnetic field of induced current is opposing the rotation (lenz law) , but if that magnetic field is cancelled by another adjecent rotor, then the question is will the generator rotor move freely in the field (the diagram shows only half a turn in each rotor, so please imagine more turns) .

Your thread will remain closed. We do not allow challenges to mainstream science here. We do allow sincere questions about basic E&M, with the intent being understanding E&M better. Please PM me if you want to continue this discussion. It is too big of a potential waste of time to leave as a general discussion item. Thank you.
