What is the difference between a magnet and a magnet?

The difference between a magnet and a magnet is that
1. Concept. Magnet is the iron transformed by the magnetization process in modern industry, that is, the iron that has obtained magnetism through technical means. Magnet is a natural magnetic stone, that is, a natural ore. It can be known from the concept that the magnet is "iron" and the magnet is "stone".
2. Components. Magnets are mostly made of iron (Fe), nickel (Ni), cobalt (Co) atoms and their alloys. And magnetite, its composition is mainly ferric oxide (Fe3O4). In terms of composition, the two are also different.
3. Shape. Magnets are synthesized into iron materials through technical processes in the later stage, so they can have a variety of shapes, such as square magnets, tile-shaped magnets, special-shaped magnets, cylindrical magnets, ring magnets and square bar magnets, etc. People will According to your actual needs, get the shape of the magnet that can meet the process requirements.
The magnetite is a kind of natural ore, so it will naturally have a messy appearance. The overall appearance is irregular block, or roughly square, or roughly round, or roughly triangular, with more edges and corners, and the cross section is not neat.
4. Magnetic size. For magnets, to a certain extent, according to the product process requirements, the magnetism can be changed from small to large, and people can manufacture a certain magnitude of magnetism. While the magnetism of magnets is fixed, the magnetism of their species is usually weak.
5. Magnetic permanent. Magnets cannot be permanently magnetized, especially the electromagnet, which can only be magnetic when energized. But magnets can always be magnetic.
6. Application. Magnets have a wider range of applications. In household appliances and even satellite missiles, etc., you can see magnets of various shapes participating in it. Magnets are mainly used in daily life as an auxiliary health care method in traditional Chinese medicine. From the perspective of Chinese medicine, magnets have the effect of harmonizing the human body.
