Why are magnets magnetic?

The iron absorption of NdFeB magnet is determined by the characteristics of the magnet. If it is explained by atomic current, it is the magnetic field generated by current magnetizing other objects magnetizing objects to generate electric field and electric field interaction to generate force. Substances are mostly made up of molecules, molecules are made up of atoms, and atoms are made up of nuclei and electrons. Inside the atom, electrons spin and revolve around the nucleus. Both of these movements of electrons produce magnetism. But in most substances, the direction of electron motion is different and chaotic, and the magnetic effects cancel each other out. Therefore, most substances do not exhibit magnetism under normal circumstances. Iron, cobalt, nickel or iron oxide

Therefore, most substances do not exhibit magnetism under normal circumstances.

Ferromagnetic substances such as iron, cobalt, nickel or ferrite are different. The electron spins inside it can be arranged spontaneously in a small range to form a spontaneous magnetization region. This spontaneous magnetization region is called magnetic domain. After the ferromagnetic substance is magnetized, the internal magnetic domains are neatly arranged in the same direction to strengthen the magnetism and form a magnet. The iron absorption process of the magnet is the magnetization process of the iron block. The magnetized iron block and the magnet generate attractive force between different polarities, and the iron block is firmly connected to the magnet."Stick" together. Let's just say magnets are magnetic.
