product composition and characteristics

the internal structure of atoms such as iron, cobalt and nickel is special, and the atoms themselves have magnetic moments. In general, the arrangement of these mineral molecules is chaotic. However, their magnetic regions influence each other and cannot show magnetism, but under the guidance of external force (such as magnetic field), the alignment direction of their molecules will tend to be consistent, and their magnetism will show, it is commonly known as a magnet. The magnet is divided into permenent magnet and soft iron, permenent magnet is added with strong magnetism, which makes the spin of the magnetic substance and the angular momentum of the electron arrange in a fixed direction, while the soft magnetism is added with current (also a method of adding magnetic force) if the soft iron is removed by equal current, it will slowly lose its magnetism.

Magnetism and function of magnet
magnets can generate magnetic fields to attract ferromagnetic materials such as iron, nickel, cobalt and other metals. Hang the middle point of the bar magnet with hairline rule. When it is still, its two ends will point to the north & south of the Earth, and the end pointing to the north is called the North Pole or N pole, the end pointing to the south is South-seeking pole or S pole. If you think of the Earth as a big magnet, the current north magnetic pole of the Earth is South-seeking pole, and south magnetic pole refers to the North Pole. Between the magnet and the magnet, the same pole is repelled and the different pole is attracted. Therefore, the compass and the South Pole are excluded, compass and the North Pole are excluded, while the compass and the compass are attracted.

Classification of magnets
magnets can be divided into "permenent magnet" and "impermanence permenent magnet". Permenent magnet can be a natural product, also known as a natural magnet, or can be manufactured manually (the strongest magnet is NdFeB magnet). Non-permanent magnets, such as electromagnets, are magnetic only under certain conditions.
