Magnet uses and operations: applied to traditional industry, military field, physical role, medical role, engineering role and so on.
Magnets are relatively large, generally able to be used in traditional industry, medicine, astronomy, military and other fields, can be applied to electro-acoustic, permanent magnet motors, communications, automotive electronics, magnetic machinery, aerospace, computers, household appliances, medical equipment, office automation, toys, boxes, leather products, magnetic jewelry and other kinds of supplies, as well as radar, communication navigation, telemetry and other electronic equipment.
Magnets are composed of iron, cobalt, nickel and other atoms, the internal structure of its atoms is relatively special, itself has a magnetic moment. Magnets are capable of generating magnetic fields and have the property of attracting ferromagnetic substances such as iron, nickel, cobalt and other metals.
Properties of magnets1, magnets have magnetic poles, each magnet has an N pole and S pole two kinds of magnetic poles exist in pairs.
2, when two magnets are close to each other the same magnetic poles will repel each other and push away, not the same magnetic poles will be attracted to each other and stick. That is, the same poles repel and opposite poles attract.
3, magnets can be divided into permanent magnets and non-permanent magnets, permanent magnets can be a natural product also known as natural magnets can also be artificially manufactured, non-permanent magnets such as electromagnets only under certain conditions will appear magnetic.
4, magnets have magnetic properties can attract iron objects.
