Magnetic energy is a newly developed energy source. This kind of energy has high efficiency and can be superimposed on other energy sources. Therefore, magnetic energy is paid more and more attention to. An electric current is established in the coil to counter the self inductance electromotive force of the coil, and the energy associated with this part of the work is called self induction magnetic energy, and the magnetizer thus generates magnetic energy. It is a device that produces a magnetic field with an electric field, so an automatic rotor winding machine is required to design the coil, which generates current in the coil to further produce a magnetic field.

When a magnetic field is produced, it is magnetized by an object that needs to be magnetized so that it produces magnetic poles and magnetism, thus becoming a magnet. This is a relatively fast process, but also a qualitative leap since the development of modern science and technology. The birth of energy led to the development of many industries, including part of the commutator commutator spot welders machinery industry of energy to join, the commutator can be more smoothly and more rapid operation, the drive motor running, so as to improve the production efficiency. Magnetic energy has led to a great variety of changes. To the urban, social and economic development, maglev train is the most beautiful scenic line between the cities.
