Although many people know about magnets, they do not know that magnets can be divided into many kinds. Moreover, there are great differences between “ordinary magnets” and “Neodymium strong magnets“. Magnets used in different industries are also very different.
1. According to the material, magnets can be divided into Nd-Fe-B magnets, ferrite magnets, samarium-cobalt magnets, and AlNiCo magnets. Among them, the popular ones are Nd-Fe-B magnets, which are called “the king of magnets” because of their super-strong magnetic force.
2. According to magnetism, can be divided into permanent magnets and ordinary magnets.
3. According to the magnetic force, it can be divided into a strong magnet and an ordinary magnet.
So what are the differences between ordinary magnets and neodymium strong magnets?
1. High-temperature resistance: The indoor temperature and Curie temperature of Nd-Fe-B magnets are higher than those of ordinary magnets. No matter which kind of strong magnet material is used, it is better than the ordinary magnet, so the limit temperature of the strong magnet itself can be greatly increased. In the industrial industry, the machine can run at high temperatures.
2. Hardness: Because Nd-Fe-B magnets increase the density of rare elements, they will be harder in hardness than ordinary magnets. Therefore, in the use process, it greatly avoids the situation of fragmentation of magnets caused by collision, while ordinary magnets are fragile, and their appearance will rust over a long period of time.
3. Strong magnetism: Common magnets on the market are determined by the number of coins they can absorb, while NdFeB strong magnets can absorb 640 times their own weight, and the magnetic force can be imagined to be how big, so when contacting strong magnets, attention should be paid to avoid being pinched by them.
4. Price: Although the magnetism of the NdFeB magnet is very strong, its price is proportional to itself.
In summary, there is still a significant gap between neodymium magnets and ordinary magnets. Nd-Fe-B magnets are generally used in electronics and other industries.
