Magnets will have a magnetic principle

Magnets  characteristics of the decision, if the atomic current is explained by the magnetic field generated by the current magnetization of other objects, the magnetic field generated by the electric field, the interaction between the electric field to produce force.

Most of the material is composed of molecules, molecules are made of atoms, atoms and nuclei and electrons. Inside the atom, the electron keeps spinning and rotates around the nucleus. Both types of movement of electrons produce magnetism. However, in most materials, the direction of electron movement is different and disorganized, and the magnetic effects cancel each other out. Therefore, most substances do not show magnetism under normal conditions.

Iron, cobalt, nickel or ferrite and other ferromagnetic substances are different, its internal electronic spin can spontaneously arranged within a small area to form a spontaneous magnetization zone, this spontaneous magnetization zone called magnetic domain. Ferromagnetic material after magnetization, the internal magnetic domain neat, aligned in the same direction, so that the magnetic reinforcement to form a magnet. Magnet iron absorption process is the magnetization process of iron, magnetized iron and magnet attraction between the different polarities, the iron firmly with the magnet "stick" together. We say the magnet is magnetic.
