Lenz's law can avoid the motor \ generator structure

[exnihiloest]

...
This is just an idea:
     We usually use the motor or generator, using the ring magnet can be rotated, instead of conventional fixed magnets, when the magnet through the coil, because of ring magnets can be rotated, the resistance of the Lenz's law can produce Magnet "homeopathic"After, the resistance can be reduced a lot.
...

When a permanent magnet rotates about its axis of magnetic symmetry, the field remains the same, there is no difference with the field of the not rotating magnet.

The only question I have is:  wouldn't the magnetic flux be variable with each passing of the rotating magnets by the coils?  Looks like it would be random!
