i am not sure all these concepts are true. based on the 2 greatest physics laws, they are true to me.

the structure of the atom, the mechanism of gravity and magnetism, the mechanism of light quanta and quantum entanglement.

the definition of energy, the sun's energy source, how energy transfer between matters.

why energy is conserved, why time travel is an illusion, why gravity has nothing to do with space and time.

i am part of the whole, just like you. we all want a better world. we should help each other to improve things.

please don't against people, against bad information and knowledge.

enjoy life, be happy!

Some matters such as iron have a special property.

When an electrical force is accelerating the electrons in the iron atoms, those electrons will follow the force direction and arrange position as dense/lose/dense/lose formation.

When current accelerating in a transformer coil, that moving electric force will accelerating electrons in the iron core, make electrons arranged into dense/loss position along the circle around the core. >>>>> south pile.

If the current changes direction, the electrons in the core will positioning as loss/dense/loss/dense formation along the circle around the core. <<<<< north pole.

Rings of clockwise circling positive/negative force lines are stored in south pole plane. count clockwise circling positive/negative force lines rings is stored in north pole plane. We call it a magnetic field.

There is no field but force. The attitude of the dense/loss, the positive/negative arrangement is proportional to the strength of the magnetic force, so-called magnetic field strength. 

We can say that on the plane of a pole there are rings of circling force lines. Those rings are clockwise at the north pole, counterclockwise at the south pole.

When a charged particle is moving on the pole plane, the magnetic force induces a force on the particle at the radius direction. there is no field to deflect moving charges but rings of circling electric force lines.
