Hi Terrry,

In the scenario described above, if electron velocity is calculated to be around 0.7 mm/sec (presumably at a stationary position) why don't the effects of magnetism increase dramatically if we were to make a electromagnetic coil and spin it at say a lazy 60 rpm, a very slow revolution. I presume spinning an electromagnetic coil at such a slow speed doesn't increase the effects of magnetism one whit.

Just curious.
