The magnetic properties of minerals can be classified into ferromagnetic, medium magnetic, weak magnetic, and non-magnetic depending on the strength of magnetic properties. Magnetic force is a kind of interaction force. The magnet itself does not have magnetic force. It is the result of interaction between two magnets, which can be expressed as repulsion and gravity. Therefore, it can only be said that the magnets of the magnet have the strongest magnetism, and it cannot be said that the magnet has the largest magnetic force. When it comes to the nature of the magnet, it must be said that the magnetism, when it comes to the interaction between the magnets, should be said to be magnetic.
