Truly what is black hole?

In simple way, black hole (positively or negatively charged space magnetic force)

Is a fight in between two very powerful magnetic couple that is fight in between galaxy and empty space magnetic force (Positively charged space magnetic force)
Magnetism and space.
Magnetism plays very important role in true science because atom is only magnetic and all the working principle of solar system is the result of magnetic forces and magnetic flux of galaxy to sun, sun to planet, planet to moon, planet to nucleus and nucleus to electron.

All the atomic magnetic force is linked and controlled by its superior atomic magnetic force which is near to it. So this link reaction in magnetism is like chain reaction which takes place from empty space magnetic force to electron magnetic force. It works like a chain reaction in a family. To understand this space magnetism, one must have good knowledge in ordinary magnet.
Yes to understand magnet i have found new true law of permanent magnet. So please
Check my true law of magnet
