...
The energy required to saturate a small area of the core to reduce the inductance of the entire core may be far less than the energy returned if a small current was applied to the windings just before releasing the small saturated area.

This statement is verified neither by measurements nor by a theoritical analysis.

A ferrite is saturated only along the saturating field (a toroid coil saturated by a well balanced transverse field keeps the same inductance). This means that the saturating field must have components that superpose to the field that we want control. Therefore the sources of the two fields are coupled and interact on each other. The work done to control the direction of the magnetic domains by the saturating field opposes the work done by the controled field, the laws of conservation (momentum, energy) and Lenz law still apply.

You may be entirely correct, however, using a permanent magnet to cause the spot saturation does not require any energy. The magnet self attracts to the core and takes less energy to remove it from the core because of the same reason you have stated above.

After winding a toroid to 15H and taking another toroid and cutting it in half, then winding over twice the windings on the same core material only to find it tests about 10mH, it seems the toroid is self reinforcing the field.

Using a small magnet to saturate a small part of the toroid appears to cause the same action as removing a section or opening the toroid. This causes the 15H toroid to drop to about 200mH.

I am still looking for any significance in this effect or a way it could be used for any advantage.

but removing the saturation requires energy.
It is the same old reason why we have not yet seen a working PMM. The energy provided or required by the motion of a permanent magnet relative to a ferromagnetic object is the same as the work provided or required by a mass going up or down in a gravitational field, question of potential energy depending on the object position relative to the source of the field.

When a toroid is saturated and the saturation produces an effect on the inductance, the phenomenon of induction is also working: the changing saturating field induces an emf in the coil, even if the coil is a toroid (because the toroid in no more balanced, it is no more magnetically toroidal due to irregular permeability along it).
Then Lenz law applies as well as coupling with possible other external coils or magnets.

A new public demo is scheduled this week-end:
http://www.innovationdublin.ie/index.php/festival-2010-events/solid_state_orbo_demonstration/

Still keeping an open mind. Nevertheless I hope it will be more convincing than the previous demos, where no evidence but specious measurement protocols were given.
