Reset magnet, composed of atoms such as iron, cobalt, nickel, etc., has a unique internal structure and inherent magnetic moment. Magnets can generate a magnetic field and have the characteristic of attracting ferromagnetic substances such as iron, nickel, cobalt, and other metals.

Types of Magnets: Shape Magnets: Square Magnets, Tile Magnets, Irregular Magnets, Cylindrical Magnets, Ring Magnets, Disc Magnets, Magnetic Rod Magnets, Magnetic Frame Magnets, Attribute Magnets: Samarium Cobalt Magnets, Neodymium Iron Boron Magnets (Magnets), Ferrite Magnets, Aluminum Nickel Cobalt Magnets, Iron Chromium Cobalt Magnets, Industry Magnets: Magnetic Components, Motor Magnets, Rubber Magnets, Plastic Magnets, and so on. Magnets are divided into magnets and soft magnets. Magnets add strong magnetism, which causes the spin of magnetic materials to align with the angular momentum of electrons in a fixed direction, while soft magnets add electricity. (Also a method of adding magnetic force) Removing soft iron with equal current will gradually lose its magnetism.

Hang the midpoint of the bar magnet with a thin line. When stationary, its two ends will point towards the south and north of the Earth respectively. The end pointing north is called the North Pole or N Pole, and the end pointing south is called the Guide Pole or S Pole.

If we imagine the Earth as a large magnet, then the Earth's magnetic North Pole refers to the South Pole, and the magnetic South Pole refers to the North Pole. Between magnets, the same named magnetic poles repel each other and the opposite named magnetic poles attract each other. So, the compass repels the South Pole, the North Pole repels the North Pole, and the compass attracts the North Pole.

Classification: Magnets can be divided into "magnets" and "non magnets". Magnets can be products, also known as magnets, or can be artificially manufactured. Non permanent magnets, such as electromagnets, only exhibit magnetism under certain conditions.
