Permanent magnets and the non-magnetic fraction permanent magnets. Permanent magnets may be a natural product of tile magnet, also known as lodestone, also be made artificially produced (the strongest magnets are NdFeB magnets). Non-permanent magnet is heated to a certain temperature suddenly lost magnet magnetic tile quality, which is due to the large magnet arrangement consisting of "meta magnet" and from order to disorder caused; demagnetized magnets placed in a magnetic field when the magnetization reaches a certain value, it is magnetized arrangement "Yuan magnet" in and from disorder to order. In fact, not a permanent magnet permanent magnet external factors will not only change the magnetic high temperature, impact will it loses its magnetism, strong magnetic fields can also change its magnetic poles and the strength of the magnetic field generated by an alternating current changes in the size of soon be to the magnetic body. 7. Q: Under high temperatures, will be the choice of what kind of magnet? A: The maximum operating temperature of each magnet is roughly as follows: aluminum-nickel-cobalt (500 ° C)> samarium cobalt (300 ° C)> ferrite (200 ° C)> NdFeB (80 ° C) in accordance NdFeB different performance, highest currently developed EH magnet can reach 200 ° C tile magnets price, but according to the specific shape and size of the magnet may be, the mall NdFeB products available maximum operating temperature is 80 ° C tile magnet factory outlets, such as the need for higher operating temperature can be customized according to customer requirements. 8. Q: The Curie temperature is the maximum operating temperature of the magnet it? Answer: It is not. Each magnet Curie temperature and the maximum operating temperature are not the same, at the Curie temperature, magnetic magnets will completely disappear. Each magnet has a maximum working temperature exceeds this temperature the magnetic properties will be a sharp decline, and even returned to room temperature, magnetic and can not recover faded. Tile magnet factory outlets, the new Xin Tong magnetic, tile magnet provided by the Dongguan City, Tong Xin magnetic Limited. Dongguan City, Tong Xin magnetic Limited (www.dgxtxmagnet.com/) Dongguan, Guangdong, magnetic leader, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. New Tong Xin magnetic leadership with the staff warmly welcome all inquiries to discuss, with new magnetic Xin Tong better future.
