PhysicsProf Steven E. Jones circuit shows 8x overunity ?

An increasing battery voltage does not mean the battery is gaining energy. Dozens of experimenters on this site have been fooled by this.

Right -- as I noted, this could be "battery relaxation" (for example).

With regard to the ideal toroid experiment -- I wrote,

Will the wire-loop experience a voltage and current in it, due to the nearby changing magnetic field -- even though the measured B field outside the solenoid is ZERO?

Experimentally, the answer is yes.  This phenomenon is rarely discussed in Physics classes (from my experience).  There must be some change in the "vacuum" around the toroid in order for there to be an induced current in the loop.

The question is, how is the change in magnetic field at the center of the loop SENSED by the loop, when the magnetic field outside the toroid itself is ZERO?    There is no magnetic field to affect the electrons in the wire, from the toroid, just an electric field.  And does this electric field propagate outward from the toroid at the speed of light?  I suppose so.

I'm hoping Frankly will consider the appearance of the electric field outside the toroid in the absence of a magnetic field outside the toroid, in his theoretical model.

  For those that have not seen Koolers bwjt video lighting 70 leds at 27mA:

  Sorry for the double post...  I hit the post button and nothing happens, so I hit it again, and...

   There may be a lot more to "battery relaxation" than meets the eye.  As both capacitors and metal cased batteries display this same effect to a certain degree.  I believe it to be caused by aether absorption pulled in by the device.

I do not think the magnetic field outside of the solenoid is zero. I think that if a compass is brought near either end of the solenoid it will show a magnetic field. These field lines are continuous and go from one end of the solenoid to the other end. There does not appear to be a magnetic field close to the sides of the solenoid because the fields cancel each other out there. Note, I am posting this without checking to make sure I am correct, so I could be wrong, but I do believe this is correct. For a toroid, the magnetic fields are all (almost all) contained inside the toroid since it has no open ends.
