Attached image is my interpretation. Red is the coil wound toroid. So you have magnetic field going vertically from one magnet, through the toroid, and into the other magnet. The amount of field going through the toroid depends on the toroids effective perm. Apply current through the toroid windings for typical magnetic material will decrease the toroid perm. Magnets rotate away from the toroid, thus requiring less energy to escape.

Trust me, there's a lot more details involved. The magnet also changes the effective perm for the toroid. If everything's not right, then there's a big loss in toroid due to a change in perm.

A little more details. After applying current in the toroid, half of the toroid perm increases and the other half decreases for typical material. When the magnet leaves the perm changes once again.

Where can someone buy good priced bearings in north America?

Hi Paul,

I've been pleased with bearings from www.bocabearings.com

Thanks. Do you inject your own lub in the bearings?

Regarding @alsetalokin's (TinselKoala) back emf (BEMF) experiment:

This is an example of bad science: http://www.youtube.com/watch?v=js24ZZ_6Je0.

Change of magnetic flux that is supposed to cause the BEMF, which is the main focus of attention here, is the change of flux caused by the pulses of current flowing through the coils. Thus, it is the emf causing these current pulses through the coils that is the subject of study here. Whether or not there is a permanent magnet nearby these coils is only a condition which may or may not change the studied emf. If that studied emf changes then there is BEMF generated. If that studied emf doesn’t change then there is no BEMF generated. In Steorn case the studied emf remained the same throughout the entire experiment despite the presence of permanent magnets near the coils and even despite their turning at various rotation rates.

Emphatically, the subject of study here is not the change of magnetic flux due to the motion of a permanent magnet that is supposed to cause emf (BEMF) in a nearby coil as the author of the video http://www.youtube.com/watch?v=js24ZZ_6Je0 really wants us to believe. The gingerly activity of this author in the forum, supported by another ginger activist, will not change above fact and anyone caring for the scientific side of this debate should take note.
