Nd-Fe-B magnet is a kind of magnetic material widely used. Although the original magnetic materials came from nature, they have been applied to various industries with the improvement of science and technology, giving play to their potential value. They have played their divine power in electronics and military. With the development of computer, communication and various electronic products, rare ...
Magnet is used in many places in the home, it is actually in every corner of our life, but we do not find it. Why is it so widely used? Because a lot of electrical appliances if there is no magnet, there is no way to work, I will introduce some common products to you from several aspects, you can have a look! 1. Microwave magnet: Almost every family has a microwave oven, which brings a lot of conv...
Many people know that the characteristic of magnets is that they can absorb iron. Magnets can be used in many ways. How long magnetic properties last is perhaps a matter of concern. Many people say that magnets can convert electrical energy into mechanical energy and mechanical energy into electrical energy. Because of this, the position of magnet in modern industry is irreplaceable. It is widely ...
Can neodymium iron boron powerful magnet really cure diseases? According to the literature, China is the first country in the world to discover and apply magnetic field to treat diseases. Magnetic field treatment can be traced back to more than 2000 years ago. According to the records of the historical records, some people used magnets to treat diseases in the early Western Han Dynasty, but due to...
1. The magnetism of neodymium magnet is super strong.You should avoid holding hands or other parts of your body with magnets.Especially magnets with large volume and strong suction.Don't swallow a strong magnet.If swallowed carelessly, go to the hospital for treatment immediately.Strong magnets should be kept out of the reach of children. 2. Do not place strong magnets near electronic medical...
When it comes to the relationship between temperature and magnetism, we must first understand a concept-"Curie temperature".More than 200 years ago, a famous physicist Pierre Curie，discovered a physical characteristic of a magnet in his laboratory, that is, when a magnet is heated to a certain temperature, its original magnetism will disappear. Later, people called this temperat...
Surface magnetism, also known as surface magnetic field, refers to the magnetic induction intensity at a certain point on the surface of the magnet, and the unit is Gauss Gs or Tesla T (1T=10000Gs). The parameter of surface magnetism is easy to measure. When the size of the magnet is determined, people often judge the performance of the magnet by comparing the surface magnetism. When encountering ...
People familiar with magnet materials must have heard of Al-Ni-Co magnets. Alnico permanent magnet material is an alloy composed of metal aluminum, nickel, cobalt, iron and other trace metal elements. Al-Ni-Copermanent magnet material is the earliest widely used permanent magnet material, and its preparation process and technology are quite mature. Before the discovery of rare earth perm...
