Rotating magnetic fields

Here are some good links to help people understand "rotating magnetic fields" for those attempting to recreate SM's TPU:

 I'm just going to drop this in here and back away slowly. This is just a link for your refrence files http://www.nr.titech.ac.jp/~htsutsui/study/SMES/
  Babelfish it. It basically deals with SMES (found through google image search of same). Superconductive Magnetic Electrical Storage.
  The idea is to put a current into a SC'ing toroid coil and just let it go round and round, until tapped off for power. They want to put a lot of current in, and the physical forces imparted by the current literally vibrate the torroid apart. You must dig a ditch, line it with concrete and squeeze the coil in there...holding/supporting it tightly. This is no good for a portable unit, so they wind the coil quasi-caduceus style, with two windings, in opposite directions, in order to balance out the forces. Notice that the windings do not cross at 90 deg's like a pure caduceus would. They worked out some other angle of "X" overlap that works better.
  In the images they show you very clearly which way the various forces in a traditionally wound toroid act to flex the structure.  This may be of help in visualizing the dynamics of the physical vibrations some of youze are getting in your TPU's.
  I guess this is just another way to skin a cat, but perhaps a way no one has tried in a TPU? And, if there is a way to get a rotating field from a dc coil, every variation of coil and many variations of current(s) are going to have to be tried.
  Just another one for the 'to-do' box
P.S. Continuing my phi phascination, I'm wodering if the clamied 'perfect damping' of phi is supported by this new 'X' angle...is it a phi-related angle?

reminds me of Walter Russell's books on cosmogony and how there are two opposing helical forces...electric current has this same structure.

When I mentioned "phi", I meant the "electrostatic scalar potential".  There is also "E", the "electrostatic vector potential" which is moving and creates the infamous "A-field". 

"phi" is the "time" component of the EM four vector, ala Einstein and friends.

Since the two electric fields can exist without the magnetic fields - they become quite interesting.

EDIT:

For example:

at the end you see:

The electric field induced by time-varying magnetic fields is non-conservative, and is described by the magnetic vector potential "A".

Here is a decent image of the fields around a moving sheet of charge.  Keep in mind that the magnetic field of a sheet of charge does not drop off with the square of the distance like the field around a wire does. Also, the A-field does not follow the square fo the distance rule either.

Anyone seen this?
