The use of magnets in our lives is very extensive. Usually we all know that magnets are often applied to toys and purses, and there is another type of magnet called a clothing magnet. Did you know? Do you think that kind of magnet is used in that respect when you hear that name?
Garment magnets produce magnetic fields that attract ferromagnetic materials such as iron, nickel, and cobalt. Suspension of the midpoint of the bar magnet with a thin wire, when it is stationary, both ends of the bar magnet will point to the south and north of the earth, the north end is referred to as the north pole or north pole, the south end is the south pole or S pole. If you think of the earth as a big magnet, then the current geomagnetic North Pole refers to the South Pole and the South Pole refers to the North Pole. Clothing magnets and magnets, the same phase exclusion, the other phase attracted. Therefore, the guideline is very pole of exclusion from the guideline, referring to the exclusion of the North Pole from the North Pole, and the South Pole and the North Pole. Without magnetic materials, electrification becomes impossible, because generators use generators, transformers use transformers, and electric machines use motors, telephones, radios, and televisions to use loudspeakers. Many instruments have to use magnet coil structure. All of these have already been said about other things.
The application of magnet, far more than we know the scope of much more, maglev train is a very typical example. Relying on magnetism to drive train operation not only achieves a very high standard of speed, but also guarantees its safety.
