MAGNETISM
2 parallel wires at r distance, the free electrons in the 2 wires repel each other with force f=Ke x q1q2/rr, that force is the conductor of induction, it transfers emf/energy/moving electric force. if electrons accelerate in wire 1, electrons in wire 2 will instantly have opposite direction emf induction. same as momentum conservation.

Before magnetize, atoms in the magnet are all neutral. After magnetize, atoms become magton line up into concentric rings all across the poles. Every magnetic atom/magton contains 2 atoms. 2 atoms of a ferromagnetic matter before magnetize, we put it as 00. if 1 electron moves from 1 atom to the next atom and stays there as -1+1, the 2 atoms become a magton, it carries a special property now, we call it magnetic force. -1+1, -2+2, -3+3...-n+n are all magtons but carry different magnetic force strength. Same direction magtons attract and opposite magtons repel. Use copper wire winding around an iron core, put a current, the electrons in the wire move in circles around the core, induced emf in the core make atoms in the core arrange into -1+1, -1+1, -1+1 directions all the way through, on the north pole plane, magtons are arranged into clockwise concentric circles of -1+1, -1+1, -1+1 direction. On the south pole plane , magtons are arranged into counterclockwise concentric rings of -1+1, -1+1, -1+1 direction.
there is only 1 force exists, coulomb force f=Ke x q1q2/rr. gravity and magnetic force are both different configurations of electric force. without matters, there is no force. a single matter has no force. force can only exist between matters. without a test body, where is the electric or magnetic field? where is gravity field? the mysteries of the universe are within 2 equations. f=Ke x e1e1/rr and f=G x m1m2/rr. those 2 forces rule everything existing. the mechanism of quantum entanglement is simple. the force between any 2 charged particles f=Ke x qp/rr is the carrier of energy/information/moving electric force/emf. it is as an invisible physical rod with zero mass that always connected 2 particles as 1. if 1 particle is energized, that energy instantly transferred to another. from f=ma, m=0, so energy instantly moved from 1 particle to another.
