Maglev train is a high speed maglev train system with a touchless magnetic levitation, guidance and drive system.   It uses contactless magnetic forces to lift the entire train, freeing it from the friction of traditional train tracks and moving at much faster speeds. Maglev train has the advantages of fast speed, strong climbing ability, low energy consumption, low noise during operation, safety and comfort, and no harmful substances. It uses an elevated mode and occupies a smaller area, which can provide a more stable riding environment.   Trains built using contradictory basic principles are called maglev trains, and contemporary luxury cars require 15-70 permanent magnetic machines. For example, wind damper motor, gasoline pump motor, window open motor, anti-theft lock motor, fog motor, car controller, starter and so on.

In wind turbines, magnets are mainly used to generate magnetic fields to achieve the conversion of electrical energy. The rotor in the generator contains a set of magnets, and the stator contains an electric coil. When the magnet in the rotor rotates, the electrons in the electric coil move with it, resulting in a current output. Therefore, magnets play an important role in wind turbines, which can generate a constant magnetic field, so as to achieve the output of electricity.

  The electric permanent magnet claw hand works with the robot.   There are many applications of electric permanent magnets in robots, and electric permanent magnets claw hands cooperate with robot operations, completely changing the traditional handling mode, improving work efficiency and ensuring product quality. With the continuous development of Industry 4.0, industrial robots are becoming more and more popular in the manufacturing field, transforming intelligent production operations and helping enterprises transform from traditional ones. In the processing and manufacturing industry, the application of robots are arc welding, spot welding, laser welding, laser cutting, machine tool loading and unloading, forging, stamping, assembly, sorting, etc. Each process runs through the entire process, different industrial robots to complete different processes.     For sorting, loading and unloading, handling and other operations, the electric permanent magnet claw hand evenly adsorbed the workpiece through the magnetic force, will not drop or damage the workpiece, fast translation and turnover action, to adapt to different workpieces and working conditions. Thus improve enterprise efficiency and core competitiveness!

Nuclear magnetic resonance is a physical phenomenon that involves the interaction between the spin of an atomic nucleus and an applied magnetic field, which causes the nucleus to resonate. In medicine, magnetic resonance imaging (MRI) uses this phenomenon to obtain image information inside the human body.   An electromagnet is a device that uses an electric current to create a magnetic field. It is usually made of a solenoid or coil that attracts or repels objects through a magnetic field generated by an electric current. Electromagnets are often used in electronics, communications, energy and other fields.   In magnetic resonance imaging, a strong magnetic field is required to excite and detect resonance phenomena in atomic nuclei. For this reason, high-strength electromagnets are often used in MRI devices to generate magnetic fields.   Therefore, although nuclear magnetic resonance and electromagnets are different physical phenomena, in some applications, such as magnetic resonance imaging, electromagnets play an important role. Here's how NMR works:   Spin: Atomic nuclei have spin and rotate on their own axis just like the Earth.   Magnetic moment: Atomic nuclei have a positive charge and therefore also generate a magnetic field. When an atomic nucleus spins, it creates a magnetic moment, which is the strength and direction of a magnetic field.   Applied magnetic field: Under the action of an applied magnetic field, the magnetic moment of the nucleus will be changed by the action of the magnetic field.   Resonance: If the strength and frequency of the applied magnetic field is exactly equal to the Larmor frequency of the nucleus, the magnetic moment of the nucleus will resonate. In resonance, the nucleus absorbs the energy of the magnetic field and deflects the magnetic moment instantaneously.   Relaxation: When the external magnetic field no longer acts, the magnetic moment of the nucleus will gradually return to the equilibrium state, this process is called relaxation. The nucleus relaxation process is an important parameter in magnetic resonance imaging.   Detection: In magnetic resonance imaging, the detection coil is used to detect the signal emitted by the nucleus during the relaxation process, so as to obtain information about the inside of the object. Using this information, a three-dimensional image of the object can be reconstructed.

Loudspeakers are one of the most important pieces of equipment in our home sound system. Magnets can interact with coils in the speaker to produce sound. To produce a powerful sound, some small, high-power speakers use neodymium magnets. The speaker uses the magnetic field of the magnet to make a weak change in the current, resulting in different intensity of vibration, and emit different sounds.
