Strong magnet become magnetic because of what you might not understand, so quick with small make up to learn there will be the principle of magnetic strong magnets.
Strong magnet material is mostly made up of molecules, the molecules are made of atoms, atoms are composed of atomic nuclei and electrons.
From inside the atom, the electronic constant rotation, and rotate around the nucleus.
These two movement produces magnetic electrons.
But in most materials, electronic movement in the direction of each are not identical, desultorily, magnetic cancel each other out.
Therefore, most material under normal circumstances, do not present magnetic.
Such as iron, cobalt, nickel or ferrite ferromagnetic kind material is different, its internal electron spin can spontaneously lined up in a small scope, forming a spontaneous magnetization, the spontaneous magnetization area is called magnetic domain.
Ferromagnetic kind material after magnetization, internal magnetic domain uniformly lined up neatly, direction, make the magnetic strengthen, constitute a strong magnet iron.
Strong magnet iron absorption process is the magnetization process of iron, the magnetized iron and the strong magnet attraction between different polarity, iron and strong magnet is' glued 'together.
He is said to be the strong magnet magnetic
