Anyway the Force vector (u X B) for each contact side is on the
rim of the disk rotating about the axis lying on its plane and
perpendicular to the uniform magnetic field B. The vector 'u'
is also perpendicular to the plane of the disk. This then would
produce a rotational force - hence Homopolar generator.
The error I made was that the force is not "out of the disk
and perpendicular to the axis" but rather on the rim, perpendicular
to current flow, and perpendicular to magnetic field B. They
actually add together. If one was to force current the other
way the disk would turn, as a Homopolar motor would operate.

Hi Ken! I read your article, and I believe that you made a mistake when
calculating the direction of the force via the Biot-Savart law. Let's draw
a disk on a piece of paper rotating counterclockwise with the magnetic
field coming out of the paper. Examining the top of the disk, the velocity
of the particles is left and the magnetic field is out, so by the right
hand rule, the force on a positive particle is up, and therefore so is the
current. Applying the Biot Savart law with the right hand rule again on
the top of the disk, we see that if the current is up and the magnetic
field is out of the paper, then the force on the disk will be to the right,
not out of the paper as your article claims. In other words, the magnetic
field will exert a force on the disk that is tangent to the disk and in the
opposite direction from the rotation. Therefore, the two brushes cannot be
used to cancel out the force, because they will exert the torque in the
same direction on the disk.
This jives with conservation of energy; if the disk rotates through a
magnetic field, then it makes current, and that energy has got to come from
somewhere, so it comes from the angular kinetic energy of the disk.
Let me know if you have any questions or disagreements about this flaw.
Good luck on any future theories.
