Ok I have thought of an easier way to explain it...

Place a pencil on the desk in front of you, the tip pointing toward the screen and the end pointing towards you. Now move the pencil back and forth between you and the monitor. This is a linear reciprocal force.

Now take a second pencil and place it the same way but a foot to the right, what you have done here is move the coil represented by the second pencil away from the pivot represented by the first pencil. This creates a linear distance between the two and therefore a potential difference. Now stand the second pencil on its end so that the tip points towards the ceiling. This is rotating the coil through 90 degrees. You can now move the second pencil in an arc around the first pencil while maintaining the same distance between the two. This is a conversion to rotary moment.

Every time you double the distance between the two pencils you double the torque moment created on the pivot, even though the linear force propelling the second pencil remains the same. This can be imagined as trying to undo a nut with a wrench. A nut that is on tight will not budge, so you grab a power bar and double the effective length of your wrench. Now you can apply the same force as you did before but it has been magnified by a longer lever and so a larger torque moment is placed on the nut, and the nut comes loose... even though you have applied exactly the same force in both instances.

That help ?

So maybe with the coil on the rotor I could somehow separate out the electric componant?.I want a rotary electric field I believe.I want it to rotate at the speed of light .Because of this speed I wanted the Rodin coil did not seem to suit my purpose.Thats a rotating magnetic field  ( rodin).But maybe I could separate out the electric vector?. Because of the speed of light requirement it could never be a mechanical system as the energy requirement would go to infinity and the mass of it would go to infinity.I would be creating a black hole here on earth.triffid

I want a rotating electric field that spins at the speed of light or close to it anyway.I can get a linear motion to go back and forth very fast.I don't know how close to the speed of light it could go.It might get close because it would be a electronic system,nothing mechanical.Ie no black holes.triffid

My aim there is to slow down the flow of time for an object thats placed in a box.So its what I had on the back burner since 1986.So a man could step inside and look outside as things appear to him to be speeded up
while time for him flows at a much slower rate.A man would age a lot slower too.triffid

Not time travel maybe but suspended animation.Instead of freezing, suspension.
