The Poles of the Magnet

by AOMag | post a comment

The composition of the magnet is iron, cobalt, nickel and other atoms, and the internal structure of atoms are quite special,and have their own magnetic moment.Magnets can generate magnetic fields and the magnetic charges of the magnets are in the same direction, and the generated magnetic fields cannot cancel each other out, thus forming the north and south poles of the magnets.

Why do magnets like poles repel and different poles attract? The magnetic field is generated by molecular current. When the same poles of magnets are close to each other, the molecular current tends to weaken, thus generating a repulsive electromagnetic force. When the poles of the magnets are close to each other, the molecular current tends to increase, resulting in an attractive repulsive force. Simply put, the repulsion and attraction of a magnet are caused by the magnetic field in the magnet. This is also said in physics that like poles repel and different poles attract. Maglev train is based on the principle that like poles repel and different poles attract.Because magnets have two forms of repulsion and attraction, there are two corresponding forms of maglev trains:The first one is a maglev train with electromagnetic operation system designed by using the principle of like poles repel.It makes use of the repulsion force generated between the magnetic field formed by the superconductor electromagnet on the train and the magnetic field formed by the coil on the track, so that the train body floats.

The second one is a magnetic levitation train with electric power running system designed by using the principle of attraction of different poles.Repulsion levitates the train, attraction makes the train move. There are many secrets of magnets. It is like a magical existence, and it also brings convenience to our lives. If you are interested, you can learn more about it.
