How do Badge Magnets have magnetism?
In fact, the principle of the magnet is that the magnet attracting iron is determined by the characteristics of the magnet. If explained according to the atomic current, the magnetic field generated by the current magnetizes other objects. The magnetized object generates an electric field. The electric field of the metal magnet badge interacts to generate force.
Most matter is made up of molecules. Molecules are made up of atoms, and atoms are made up of nuclei and electrons. Inside the atom, the electron rotates continuously and revolves around the nucleus. Both of these movements of electrons produce magnetism. But in most materials, the directions of electrons are different and chaotic, and the magnetic effects cancel each other out. Therefore, most materials do not exhibit magnetism under normal conditions.
And ferromagnetic materials such as iron, cobalt, nickel, or ferrite are different. The electron spins inside it can spontaneously arrange in a small range to form a spontaneous magnetization zone, which is called a magnetic domain. . After the ferromagnetic substance is magnetized, the internal magnetic domains are arranged neatly and in the same direction to strengthen the magnetism and constitute a magnet. The magnetization process of the magnet is the magnetization process of the iron block. The magnetized iron block and the magnet with different polarities generate attraction between the iron block and the magnet firmly. We say that Magnetic Name Badge are magnetic.
