The composition of magnets is iron, cobalt, nickel and other atoms, the internal structure of its atoms is relatively special, and it has its own magnetic moment. Magnets can generate magnetic fields and have the property of absorbing ferromagnetic substances such as iron, nickel, cobalt and other metals. Magnet varieties: Shape magnets: square magnets, tile magnets, special-shaped magnets, cylindrical magnets, ring magnets, disc magnets, bar magnets, magnetic frame magnets, attribute magnets: samarium cobalt magnets, neodymium iron boron magnets ( Strong magnets), ferrite magnets, AlNiCo magnets, FeCrCo magnets, industry magnets: magnetic components, motor magnets, rubber magnets, plastic magnets, etc.
