The main application functions of sintered neodymium iron boron permanent magnet materials are:
1. Utilizing the strong suction force of neodymium iron boron materials on steel, it is used for magnetic suction cups, magnetic separators, leather buckles and other devices;
2. The coil with unstable current generates electromagnetic effect, which interacts with the magnetic field generated by the magnet to produce vibration. The magnet is used as the magnetic source for the horn;
3. According to Faraday's principle of magnetoelectricity, magnets are used as magnetic sources for generators, such as wind turbines and various inductive sensors;
4. According to the Ampere force experienced by charged conductors in a magnetic field, magnets can serve as magnetic sources for various permanent magnet motors, such as neodymium iron boron motors;
5. Utilizing the quantum magnetophysical properties at the atomic scale, magnets are used as magnetic sources for nuclear magnetic resonance instruments MRT.
