What is the difference between neodymium magnets and ordinary magnets, and the harm of neodymium magnets to the human body

1. What is the difference between a ferromagnet and an ordinary magnet


High temperature resistance: The indoor temperature and Curie temperature of ore strong magnets are stronger than ordinary magnets. No matter what kind of strong magnet material is used, it is superior to ordinary magnets, so the limit temperature that the strong magnet itself can withstand will be greatly improved, and in industrial industries, machines can operate at high temperatures.
Hardness: Because wrought iron powerful magnets increase the density of rare elements, they will be harder than ordinary magnets in hardness. Therefore, in the process of use, the situation of magnet fragmentation caused by collision is greatly avoided, while ordinary magnets are fragile, and other locations will also be sharp after a long time.
Strong magnetic force: Ordinary magnets on the market determine their magnetic force according to how many coins they can absorb, while wrought iron powerful magnets can absorb heavy objects 640 times their own weight. Be careful not to be caught by it.
Price: Although the magnetic force of the wrought iron strong magnet is very strong, its price is directly proportional to itself. As the saying goes, "you get what you pay for", the price of high-quality products will not be convenient.

2. The harm of neodymium magnets to the human body


The possible harm of neodymium magnets to the human body has an impact on the growth and development of the central nervous system. NdFeB magnets are widely used in electronic products, such as hard drives, mobile phones, earphones and battery-operated tools. The magnet mainly uses the magnetic signal generated to work. This magnetic effect is not very harmful to the human body, so avoid worrying too much. However, as a pregnant woman, you should stay away from magnets properly, because magnetic substances may have certain effects on the growth and development of the fetus and the central nervous system.

testimonials

client purchase strong magnets"Since 2006, we found Mr.Guo and get products from him. We used magnets under the earth for the gas and water pipe industries. We have met no problem. We have been working in very happy ways. We have many cooperation. Every year, we spent time together and sometimes, we invited him to Korea. He is our younger brother. Strongly recommended!!"

customers buy permanent magnets"I had email to Mr. Guo for rare earth magnet requirements. They replied my e-mail promptly, and were very professional. Mr. Guo’s team still continues to deliver rare earth magnets to our agreed specifications with a very high quality standard since 2012. His team is very professional and thorough with its work. Based on my experience, I would highly recommend them."
