Why the magnet have magnetic force?

Why the magnet have magnetic force? Magnet has a magnetic force is determined by the characteristics of the magnet if the atomic explanation is that current produced by other object magnetization magnetization magnetic field produces electric field interact to produce power. Material is mostly made up of molecules, molecular is 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, magnet magnetic cancel each other out. As a result, most of the material under normal circumstances, it doesn't present magnetic, foreign no magnetic force. 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 magnet magnetic domain uniformly lined up neatly, direction, make the magnetic strengthen, constitute a magnet. Magnet is the magnetization process of pig iron absorption process, the magnetized iron and magnet attraction between different polarity, iron and magnet is & other; Sticky & throughout; Together. We will said magnet magnetic magnet with magnetic force.
