A long solenoid concentrates the magnetic field (B) in it's center, thus
will concentrate free electrons in it's center:
B = uo*n*I Tesla
Thus, a "Betatron-Type" hollow vacuum "Solenoid Hoop" with injected free electrons
circulating around the minor axis at 3.0 million meters per second might show an
antigravity force of about 85 pounds. Or Much Less. :-)
In order to get the electron "string" to circulated at 3.0e6 meters/second a potential (V) of
26 volts created by a changing B field:
V = dB/dt 0r 26 = dB/dt
1,000 turns at 1.0 ampere around a hoop with a circumference of 1.0 meters gives a B field of 1.25
millitesla or 12.5 gauss. Pulsing the field,above a fixed DC bias current that keeps the e-beam centered
against the gravity force, with a repitition rate of a few kHz should maintain the
3.0e6 meter/sec electron circulation velocity.
IMHO , this Is Not the same as an electrical conductor where charge is moving at c, but
the electrons are moving with a drift velocity of centimeters/second, or is it? :-)
