Magnetic Field Development Of Ndfeb Magnets

Nov. 16, 2019

A strong magnet is a neodymium iron boron magnet. Compared with ferrite magnets, AlNiCo, SmCo, the magnetic properties greatly exceed those of other magnets. NdFeB magnets can absorb 640 times their own weight, so NdFeB is often used by outsiders. It is called a powerful magnet. Commonly, there are Block Neodymium Magnet, square neodymium magnets, and the like. NdFeB magnets are magnetic devices, currents, stress strains, temperature, light, etc. that cause changes in the magnetic work of active components to be converted into electrical signals. In this way, devices with corresponding physical quantities are viewed. It is characterized by non-contact measurement, viewing signals are not affected by the measured object, pollution resistance, strong noise, reliable operation even under harsh environmental conditions, durable and long life. Because of this, these sensors are used in many aspects, from defense and aerospace to various sectors of the national economy, from health care to the normal days of human beings.

NdFeB magnets are usually assembled inside machines and equipment. The modern machine is agile in the direction of small, simple, multi-functional, intelligent, and pleads that the sensor used can make a high degree of activity and high speed even if it changes the physical quantity in a small space. That is, the sensor itself needs to be small and lightweight, and it is also eager to advance its working speed, viewing resolution and activity.


Semiconductor large-scale integrated circuit manufacturing technology, micro-electro-mechanical system (MEMS) manufacturing technology, micro-assembly technology, magnetic film, amorphous, multilayer film, nano-magnetic wire and other new materials, smooth surface coil micro-magnetic device manufacturing technology and The continuous advancement of the characterization method has laid a solid foundation for the miniaturization and miniaturization of NdFeB magnets. Many new high-performance, miniaturized and miniaturized NdFeB magnets with various new effects are being continuously invested in the market. . The AMR film active components and sensors that were listed in the early stage, and the thin-film fluxgate magnetometer and wireless magnetoelastic microsensor array that will be put into practical use are typical representatives. Below, the Precast Concrete Magnet manufacturers briefly introduce the working principle, basic structure and primary technical functions of several miniature NdFeB magnets.


The development and application of the new NdFeB magnets have created infinite economic, technical and social benefits, plus the immediate completion of industrial automation, processing intensification, office automation and modernization of family days, and the immediate industrialization of society to change to the information society. The footsteps. In the aspects of traditional industrial transformation, resource exploration and comprehensive utilization, environmental protection, bioengineering, and intelligent traffic control, they will play an increasingly important role.


The above is the development of the magnetic field of the powerful magnet, I hope to help everyone.
