Are you saying this in terms of an argument one may face and have to ponder
or are you saying that the OPFHD really produces no EMF at all?

The OPFHG actually produces voltage (which seems rather amazing at
first) But if you use Lorentz arguments you have to say that since
there is no relative motion between the magnet and disk there can be
no Lorentz voltage.  Thus EITHER the field rotates with the magnet and

Do you know the meaning of "piecewise"?
