Why do magnets suck up each other?
A magnet has magnetic force, which is determined by the characteristics of a magnet. If it is explained by the atomic current, it is the magnetic field produced by the current. The magnetization of other objects will produce electric field and electric field, and the interaction of the electric field will produce the force.
Most substances are made up of molecules. Molecules are made up of atoms. Atoms are made up of nuclei and electrons. Inside an atom, electrons rotate constantly and rotate around the nucleus. These two movements of electrons produce magnetism. In most materials, however, the motion of electrons varies in different directions, and the magnetic effects cancel out. As a result, most substances do not exhibit magnetism under normal conditions and have no magnetic force outside.
Ferromagnetic materials such as iron, cobalt, nickel, or ferrite are different, and their internal electronic spin can be spontaneously arranged in a small range, forming a spontaneous magnetization zone, which is called the magnetic domain. When ferromagnetic materials are magnetized, the magnetic domains inside are aligned and aligned in order to strengthen the magnetism and form a magnet. Iron absorption process is the process of magnetization magnet iron, iron and magnet magnetized generation between different polarity attraction, iron is firmly and magnet "stick" together. Let us say that the magnet is magnetic, and that the magnet has magnetism.
