Continuing thought on experiments which appear to me to violate Newton's Third Law, Lenz's law, or that lead more directly to freedom energy. At least its fun to think and invent!
Please tell me what you think -- see sketch below.
We start with a strong cylindrical magnet (or stack of N52 neodymium magnets) - although in my original-to-me thought-experiment I began with a long cylindrical solenoid (and that should work, too).
A loop of wire is wrapped around the cylinder as shown, with a capacitor (for example) for a power source, and a radio-activated switch. In the left drawing, the current flows CW. The wire segment on the left is in a strong North B field and therefore with current flowing, feels a kick towards you, due to IxB; since the current is perpendicular to the B-field; whereas the wire segment on the right feels a kick away.
Let's let the magnets have NO conducting covering, so there are no Eddy currents to consider. Note that the B-field around each wire is azimuthal, so there should be no (or very little) effect from this field on the magnet. This is where the asymmetry comes in. (One may use the right-hand rule to check me on this.)
The rod is free to rotate, and therefore begins to rotate CW (as viewed from above). Is angular momentum conserved? how? Note that the wires on top and bottom of the cylinder are in regions where the B field is weak -- and receive very little impulse.
By putting a twist in the loop, both wire segments on the ends of the cylinder feel an impulse due to IxB in the same direction - so that the rod now on a low-friction surface moves linearly - in this case, away from the viewer. Where is the third-law reaction force? - and how is momentum conserved?
Note that one may use multiple loops of wire, increasing the effect with each current-pulse.
