Faraday's Paradox experiment

[gravityblock]

A magnetic field does move with a magnet, it just doesn't appear to rotate when the field is not changing.  Rotate a flat magnet on it's side and the field above it will change.

As for the magnet rotating when current is moving radially across the conductive disc, will it rotate if it is non-conductive?

Will the disc rotate with no brushes attached?

Doesn't the electric field from the center of the disc to the periphery polarize the disc radially?

The magnetic field does not rotate with a magnet when it's rotating on it's magnetic axis.  Rotate a magnet on it's axis and no voltage is detected on a stationary disc because the magnetic field is stationary..  A disc rotating with a magnet will have a voltage because the magnetic field is stationary and the disc is moving through the field.

The magnet will rotate when it's non-conductive when current is flowing radially through a disc.

A disc won't rotate without brushes.  There needs to be relative motion between the disc and external circuit.

The electric field in the disc will have a polarity between the axis and rim.  The axis can be negative or positive depending on the direction of rotation through the magnetic field and what poles it is rotating through.

What I'm getting at is that there has to be a transfer of momentum.

Of course, but we don't want the transfer to be against the rotation of the system.

@grumpy:

I think we need to look at the possibility of extracting the current between the rim of one half of the disc and the rim of the other half of the disc with a magnet that is radially magnetized instead of from axis to rim with a magnet magnetized axially in the conventional setups.

It wouldn't be much different than one of broli's design.  We would use a radially magnetized magnet where one half is north and the other half is south.  The radial magnet would remain stationary, the disc would rotate, and our external circuit would be stationary.  We would extract the current between the rims of both halves instead of between the axis and rim.

This would allow us to have the current flowing through the whole diameter of the disc in one direction and our external circuit would provide the return path to the other side.  There would be a counter torque on one half of the magnet and a forward torque on the other half, thus canceling each other out.  The voltage should be doubled with no counter torque.

Below is an illustration.  There is a possible problem with this design and it may not work as is.  The drawing is only showing the concept to help in the visualization.
