After a while, he connects to a battery and shows that the battery voltage is going UP rather quickly.  OK -- is this a self-runner?  or a case of "battery relaxation"? 
Note that there is a circuit diagram... and this text:

one driving (motor) bedini coil and five generating (generator) coils to BR and Cap and Its' following pulse discharge by Reed Switch to battery; the same time a bemf pulses helping to charge bttry and run motor for hours...

He notes, "and run motor for hours..." -- would it not run indefinitely if self-charging?

  Now, let us focus on the ideal solenoid and rapidly ramp up the current in its wire, and also put a loop of wire around this solenoid, shaped like an Omega symbol.  Place a small resistor across the ends of the wire loop.

  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.  This to me is one of the marvels of nature.

While the flux is changing through the coil, an electric E field is produced that encircles the solenoid. It is this circular E-field which causes the emf in the wire loop. The E field is produced whether the coil loop is there or not.

@frankly,

You misunderstood me.

Why don't you just go ahead and convey your theory as to what causes the B field?

I do not know about an open loop wire, but if a loop is placed around the solenoid I believe current will be induced in it because all of the flux in the solenoid is still going through the center of the added loop. I have several car ignition coils that are built this way. Did I misunderstand your question?

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