Magnetic flux motor just patented that creates it's own electricity!

Basically everyone in the scientific/engineering world would disagree but I say let's go there...

AC

Here are some more scientists/EEs that do not disagree with me--the real ones.

It is not the magnetic field that creates current flow, it is the electric field.
The magnetic field around a conductor is a by-product of current flow, which was created by the electric field.

Here are the steps--
1- an electric field is applied along the length of a conductor in a circuit.
2- this applied electric field causes current flow through that conductor.
3- this flow of current creates a magnetic field around the conductor.

This is why the voltage (electric field) always leads the current, which means it always leads the magnetic field built by that flow of current.

FWIW, one might wish to look at the attached paper by Edwards and Saha on their position that the transfer of power from secondary to primary is via the Poynting vector or S=EXH.  IOW, the current flow in the secondary is the cross product of the E field and the H field.

Please note the toroid example near the end of the paper.

In near field coupling, i would agree.
But AC's example has the secondary in the far field, where the H field dose not exist or link with the secondary.
The paper also seems to indicate that the H field in the near field also dose not link with the secondary.

To quote that paper--Quote:  (This H field enters the core just
below each primary turn and returns to circulate
around the outside of the secondary. The resultant
leakage flux flows around the outside of the secondary
winding and does not link with it.
Most of the power (P) will flow in the inner space of
the toroid where the E field is greatest)

The magnetic field does not exist except as a closed loop.
If you wind the torroid primary over only a short area, it will still induce current into a secondary on the side opposite of the primary.

The question is, how did the loop get into the secondary on the other side?

1: It just left one end of the primary and went around the core returning back into the primary.
2: It expanded a loop as the primary current increased until it cut through the secondary winding.

Ok, here is what happens in this case.

1-an EMF (voltage) is dropped across the primary coil
2- this electric field now exists along the entire length/turns of the conductor windings.
3- this electric field starts to push the electrons through the windings
4-current starts to flow
5-a magnetic field starts to build around the windings, due to this current flow
6-this increasing magnetic field induces a counter EMF, and also starts to travel around the core.
7- this changing magnetic field enters the secondary windings on the other side of the core.
8- an electric field always travels with a changing magnetic field.
9- this electric field once again, induces a current flow in the secondary, in the very same way it did in the primary.

Magnetic fields do not have a flow, such as indicated by the pretty pictures of magnetic fields.
Magnetic fields do not induce the current flow in a conductor. It is the electric field that accompanies a changing magnetic field, that pushes the electrons through the conductor, inducing current flow. Once current starts to flow, a magnetic field builds around the conductor, which apposes the original magnetic field.
