before I go into this please allow me to explain I don't know where else to ask this, so I am asking here. I have had this idea for a few years now and I cannot figure out if I am correct, in what I assume will happen under these conditions

1. The problem statement, all variables and given/known data
Well the idea is this, if one has a ring 2 meters in diameter, with electromagnets evenly spaced along the ring, and has every thing set up so that the magnets turn on and off in sequence at near light speeds:
A. will the magnetic field from one magnet move to the next apposed to collapsing
B. what effect if any would this have on an object that is inside of the magnetic field, but stationary in relationship to the ring(not following the magnetic field)

2. Relevant equations
here I am not completely sure but I would imagine that equations dealing with temporal dilation effects of relativistic speeds, would be useful, as well as any thing pertaining to the conversion of energy into matter and the gravitational field associated with those amounts of mass

3. The attempt at a solution
it depends on if a magnetic field has the same effect on space/time that an object does, as far as I can tell one of three things will happen
A. nothing
B. time will move more slowly in the field
C. time will move more slowly, and a huge gravitational field will be generated crushing the device/planet
