What is magnetism? Facts about magnetic fields and magnetic force

Magnetism is a fundamental force, that reacts with the electric fundamental force. The magnetic force, sets the confinement, the size, and the density of the electric field. This confinement can only be set at certain fixed sizes. They call this the "quantum effect" But it's a purely mechanical dynamic.

"magnetic fields are created by moving charges" is extremely incomplete and very mis-leading. First of all, an electrically charged particle, whether in an atom or not, is always moving. It rotates. And it always has a magnetic field. The magnetic field is what holds the particle together. The rotation of the charge always is at c speed. The magnetic field, can set the size of the rotation. That sets the density, or the energy level of the charge.

When you put current thru a wire.....the current, simply aligns the field, which is already there, it just wasn't aligned. The same charge and the same M field is always on the wire, just not aligned. More current.....more alignment.

The properties of electricity and electronics, comes from the alignment of charge, not the current. The current is used to align the charge fields, which collectively, transport power or information.

The current hardy moves at all. It's an intermittent flux. But the field variation of the current, can move very fast......and appear to be instant. It's the ripples in that field, and the intermittence(AC) of the field that does all the work.
