1) The rare earth permanent magnet motor has no excitation coil and core, no loss, no heat, etc. instead of the common motor, which can reduce the volume, reduce the weight and improve the efficiency. For example, if a permanent magnet motor is used in a car to replace a conventional motor, the volume can be reduced by 40% to 70%, the efficiency can be increased by more than 50%, and the copper can be saved. By replacing the electromagnets of electromagnetic switches and solenoid valves used in a large number of electrical equipment with Permanent magnets, the power can be saved by more than 90%.

2) Using the principle of magnetic levitation to make a new frictionless bearing to replace the traditional bearing, its energy consumption can be reduced by more than 90%.

3) Using magnetic fluid to generate electricity, when the high-temperature high-speed airflow passes through a strong magnetic field, the airflow becomes a plasma electric potential line to generate an induced potential and electric energy due to the high-temperature ionization.
