Ordinary everyday life, Hall induction ring supplier is a very common thing. And thousands of years ago, workers in Our country produced one of the four great inventions, the compass, based on the characteristics of magnets. To this day, magnets are also particularly effective. Magnets can be found in all kinds of unique electronic products, as well as small toys, which are everyday teaching tools. The small pieces of metal material sucked on top are rubber and plastic magnetic wholesale. It is also an element that, along with iron, cobalt and nickel, is attracted to magnets and is being used to improve mri imaging. We know that the main component of magnets is iron tetroxide. An ordinary small magnet is made of gray-black iron tetroxide. However, due to the characteristics of ferric oxide itself, hall induction magnetic ring wholesale causes its adsorption force on iron objects is not easy to be too strong, and its magnetic band will continue to weaken gradually with the passage of time. So how do you make a magnet that is stronger and less susceptible to decay? Under such conditions, Ndfeb magnet should be born in time. This type of magnet with a shiny anti-corrosion solution is Ndfeb magnet, whose chemical equation is Nd2Fe14B. The most common Ndfeb magnet is made of neodymium, iron and boron calcined at high temperature. It is a synthetic magnet with strong magnetic field so far. If the key element of traditional ferric oxide is iron, then Ndfeb magnet often has such a strong magnetic, is the effect of neodymium element. Neodymium (pronounced nǚ) is the fourth member of the Greek lanthanide family, and like iron, cobalt, nickel and previously mentioned gadolinium, it can actually be attracted to magnets. In addition, neodymium is one of the more flexible lanthanides, so it is easily oxidized like iron, which is why ndfeb magnets are coated.
