Plasma magnet uses phased antennas operating in the radio frequency range to produce a rapidly rotati ng magnetic field. This rotating magnetic field preferentially accelerates electrons within a plasma to produce a DC current that can lead to the generation of a steady state magnetic field in space very much larger than can be possibly sustained by electromagnets. In the image at left, the two circular magnetic field coils located inside the blue plasma are driving ro ughly 1000 Amp currents in the blue plasma. This Plasma Magnet has come into equilibrium with an externally applied magnetic field.
However, a team led by Ruth Bamford of the Rutherford Appleton Laboratory and York University has shown that it is the electric field associated with the shock formed when the solar wind interacts with the magnetic field that deflects the particles bombarding the Moon.
The one difference Iv found between a magnet and a coil,
the applied current is moving right across the coil this makes north up but the A vector field is moving opposite the applied field
The same is true for a coil if the current is moving to the right north is up and on our planet our spin is from west to east and north is up, this field spins our planet. If you look at saturn you can see this field or the spiral arms of a galaxy.
Looking at the magnet can be confusing it looks as though the fields are turning opposite but when you study it its all in the perspective if your looking at the magnet from the north the field turns ccw but if looking from the south the field is turning cw.
Iv found that if you think of north up the field is moving to the right or I guess you could us that old right hand rule
While permanent magnets can't be turned off without extreme means(i.e. permanently), you can guide it's flux along ferrous (circuits) and effectively turn it off by switching it to a circuit path away from the area you want bereft of the field with a minimal pulse of power.
The electric field runs 90 degrees to the magnetic field, one of the first to discover this field was Ehrenhaft
The only way to stop a magnetic field is to shut off its power, it cant be shielded we see this with permanent magnets but the electric field can, we strip electrons from the magnetic field in our generators, passing a magnet past a copper wire will strip electrons from the field.
We just have to find a way to do it more efficiently.

Its called the A vector field, not allot of info on it but there is some, its the field that collapses into a coil and causes bemf when a coil is pulsed.

Is pretty basic the magnetic field is a charge carrier, the ions and electrons spiral around the magnetic field at 90 degrees, well I think the angle is more like 60 degrees
I happened upon this field when I started freezing coils in ice
The coil is vertical in this pic.
Since a metal detector coil is wound like a solenoid its sending the magnetic field into the ground, it all depends on how the coil is wound, like a solenoid or like a toroid.

What do you mean about "the electric field of a magnet"? I also got a question, is the working theory of metal detector is based on the "the electric field of a magnet"?
