Secret of Strong Neodymium Magnet 20151229
Neodymium Iron Boron Magnets
Permanent magnets are very commonly used in daily life. Thousands of years ago, ancient Chinese people invented compass, one of the four great inventions, according to the characteristic of magnets. To this day, magnets are very helpful to people, ranging from various kinds of special electric apparatus and common teaching aids and toys.
As is known to all, a small piece of ordinary magnet is made of black Fe3O4 which is the main component. However, due to its performance, its attractive force to iron material is not strong. Meanwhile, its magnetism recedes as time goes by. At this rate, how to produce magnets with much stronger and permanent magnetism? Neodymium magnet was born at the right moment.
With surface treatment, neodymium magnets are bright, of which chemical formula is Nd2Fe14B. Neodymium magnets are often made of neodymium, iron and boron through high-temperature sintering. As artificial magnets, they have the most powerful magnetic performance. The core element of traditional Fe3O4 is iron. Neodymium plays an important role in strong magnetism.
Neodymium is the forth element in lanthanide series of rare earth elements. Similar to iron, cobalt, nickel and gadolinium, it can be attract to magnets as well. In addition, neodymium is an active element in lanthanide series, so it is easy to be oxidized. That’s why neodymium permanent magnets have to be coated. Neodymium can improve the magnetism. However, boron’s role cannot be neglected.
In periodic table of elements, boron is at the left of carbon, so recently boron chemistry rises, similar to organic chemistry. In neodymium iron boron magnets , boron is like a mediator between neodymium and iron, which greatly expand the maximum magnetism of the object. So, the whole magnets have high performance, which even can attract the weight 640 times as heavy as itself.
