Re: Gravitation Force Between Rotating Solenoids

 the rotation of the Magnetic B Field should result in a small E field due to the acceleration v^2/r
 of the field. I.e., the tangential velocity vector is constantly changing directions. 
 Hence, two rotating solenoids should attract or repel on another with a force proportional
 to the coil current and rotational acceleration.
 
Could the "Fair Weather Field" (about 130 volts/meter at the surface, tapering off with altitude)
be due to the 1,000 mph rotation of the earth's magnetic field?

"At sea level in fair weather, there exists an average electric field of about 130 volt/m directed downward. 
The potential of the electrosphere is about 300,000 volts positive with respect to the earth's surface. 
The earth's surface contains over its entire area a net negative charge of 5x105 coulombs (or l0-9 coulomb/m2). 
An equal positive charge resides in the atmosphere above the ground."

If so, a rotating solenoid (or motor armature) should give a "pseudo antigravity" effect.

Back to the original thought.

Even if there is no E field set up around a rotating Electromagnet/Solenoid the
rotation of the Magnetic B Field should result in a small E field due to the acceleration v^2/r
of the field. I.e., the tangential velocity vector is constantly changing directions. 
Hence, two rotating solenoids should attract or repel on another with a force proportional
to the coil current and rotational acceleration.

"Maxwell's term describes the fact that a time varying electric field induces a magnetic field." 
" Faraday's law states that a time varying magnetic field induces an electric field."
There's that "rotating energy loop-disk" thingy again, Jones. :-)
