Characteristics of high-strength magnets made by magnetizers

Magnets formed by using a magnetizer for magnetization. This kind of magnets produced by high-intensity magnetization has very strong magnetism. At present, this kind of device is used in many fields. Many machines will use magnets as An auxiliary pushing device. When it comes to the use of magnets, the magnets manufactured by practical magnetizing machines are high-strength magnets. Now let's introduce the classification of high-strength magnets processed by this magnetizing machine.

    High-strength magnets include silicon steel sheets and soft magnetic cores; hard magnets include alnico, samarium cobalt, ferrite and neodymium iron boron. Among them, samarium cobalt magnets are more expensive, and ferrite magnets are cheaper. The higher performance is the neodymium iron boron magnet, and the performance is more stable, and the better temperature coefficient is the alnico magnet. Users can choose different hard magnetic products according to different needs. When it comes to high-strength magnets, this kind of magnet will be magnetized by an external magnetic field in a closed circuit environment to cancel the external magnetic field after the technology is saturated. At this time, the magnetic induction intensity of the magnet is called remanence. It represents the larger magnetic flux value that the magnet can provide. It can be seen from the demagnetization curve that it corresponds to the situation when the air gap is zero, so the magnetic induction intensity of the magnet in the actual magnetic circuit is less than the remanence, which is also some of the current high-strength magnets.
