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 carrier of energy/moving electric force. if electrons accelerate in wire 1 at 3 volts, electrons in wire 2 will instantly have 3vq1 emf. the true mechanism of electromagnetic induction. same as momentum conservation.
every magnetic atom/magton contains 2 atoms. 2 atoms of a ferrimagnetic matter before magnetize, we put it as 00. if 1 electron moved from 1 atom to the other atom and stays there as 01, the 2 atoms become a magton, it carries a special property now, we call it magnetic force.
01, 02, 03...0n are all magton, but carry different magnetic force strength.
2 magtons attract each other in the direction 01+01, and repel each other in the direction 01-10 or 10-01.
use copper wire winding around an iron core, put a current, the electrons in the wire move in circles around the core, make atoms in the core arrange into 0101 directions all the way. on the pole plane area, magtons are arranged as clockwise concentric circles of 0101 directions, north pole.
reverse the current direction, the pole plane area magtons are arranged as counterclockwise concentric circles of 0101 directions, south pole.
so, a magnet north pole stored clockwise electric force, south pole stored the counterclockwise electric force. the same poles always repel, different poles always attract.
the earth magnetic field is a mistake. there is no field but the force in the universe. sunlight moves electrons moving westward causing earth magnetic force interact with compasses.
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.
