What is the principle of magnet?

The principle of magnets can be analyzed from the molecular structure of matter: matter is mostly composed of molecules, molecules are composed of atoms, and atoms are composed 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. Ferromagnetic substances such as iron, cobalt, nickel or ferrite are different, and their internal electron spins can be arranged spontaneously in a small range to form

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.   

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.
