The way you make a photon is to change the amplitude of a magnetic field or an electric field. Either one will do it.

[Ron Hughes (OP)]

Here is a neat question. The electron has a field, how does it make that field?

[Ron Hughes (OP)]

Vern, and the amplitude of an electromagnetic wave is ,what? I forget.

[Ron Hughes (OP)]

Has anyone considered the possibility that this idea suggests inertia is also relative?

Regarding large diameter motor coupled to small diameter generator.
If the motor was twice the diameter of the generator, this would at first appear to give the motor a two to one advantage as far as leverage goes.
However, by doubling the motor diameter, this in effect halves the available finite power for the magnetic field generation, so any gain by leverage is negated here.
