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 fields 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?
