New energy vehicles refers to the use of unconventional vehicle fuel as power source (or use conventional vehicle fuel, a new vehicle power unit), integrated power control and drive of the vehicle in terms of advanced technology to form new structure of vehicles.

Electric motor refers to an electromagnetic device that can convert or transmit electricity according to the law of electromagnetic induction.Its main function is to produce the drive torque, as a power source of electrical appliances or various kinds of machinery.

Magnets can also be found in every professional loudspeaker.Magnets are a key component of sound.?It provides a permanent magnetic field for the coils in which the current is rapidly alternating with a cone that vibrates back and forth, then the audio signal comes out of the loudspeaker.

Magnets are also used in many electronic devices.As we all know, most of our kitchen appliances contain dc motors, as do electric toothbrushes.Most small electronic appliances require small dc motors to operate, and small dc motors require small NeFeB magnets.

Magnets play an important role in the renewable energy market.?Magnetic materials ?can provide different solutions in?wind energy, tidal energy fields?.By using magnets and corresponding solutions, you can reduce or even eliminate gearboxes in wind turbines.The working environment of wind turbines is very bad and must be able to withstand heat, cold, wind, humidity and even salt fog tests.

Nuclear magnetic resonance (NMR) is a nucleus with magnetic moment not zero. In the field of external magnetic field, the spin energy level is divided into a secant, and resonance absorbs the physical process of a certain frequency of radiofrequency radiation.Nuclear magnetic resonance spectroscopy is a branch of spectroscopy. Its resonance frequency is in the radio frequency band, and the corresponding transition is the nuclear spin transition on the nuclear seaman energy level.
