EXPLANATION

Field
The field is created using a permanent magnet, and is guided in two loops by magnetic material (example: soft iron).
The permanent magnet could be positioned in the centre area, where the 'N' is shown.

Conductor
The conductor is shown as a figure 8 with the centre of the '8' shorted, but could also be made from many windings, to increase voltage. For multi-turns, the wire would be wound in a continuous figure 8 with no shorted connections.

Rotation
The complete assembly is made to rotate around the axis. Use an electric drill, for example.

At the point labelled 'N', the conductor is simply a part (or segment) of a Faraday disk where the magnet is fixed to the conductor. When the conductor rotates around the axis shown, a small EMF will be generated.
The conductor, at the centre point of rotation, passes out of the magnetic material in such a way that there is hardly any field acting on it at right angles (and therefore no more EMF is generated along the length of the conductor at this point).
Once the conductor has left the region of the magnetic field it can be looped back to the point of high magnetic field again (but also with no further flux linkage).
The result is that the only point of EMF generation is in the region of the label 'N'. The conductor loops have no reverse EMF points which cancel out this original EMF.

The interesting thing is that, if the turns are shorted, then current will flow if the assembly is rotated. A back torque will be created.
The electric drill will supply slightly more power, and this power will turn the assembly. The conductor in the assembly will get hotter.

But what about the conservation of angular momentum? This assembly is resisting the turning motion of the drill. No way, surely?

Faraday disk motor

I have not seen any reference to the Faraday disk experiment in the motoring mode. i.e. fix the conductor to the magnet, and supply current to the conductor. Would the magnet and conductor turn? For the moment, I will assume that it does!
The multi-turn modification to the above idea could then be supplied by a battery which also spins with the complete assembly. Then the complete assembly can be made to turn without affecting the angular momentum of anything nearby. i.e it could start to spin in free space.
This goes against all common sense, and must clearly be wrong.

(But it would be interesting to check, all the same!)

If I ever get round to testing these ideas, then I will post the results, good or bad.
