We have been trading in the magnet industry for many years. A small number of customers indicated that the magnetic force of the permanent magnets they purchased was attenuated, and they usually suspected that it was the quality of the product itself. In fact, the quality of our products can stand the test of the market.Today let's take a look at what factors lead to demagnetization of permanent m...
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...
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 ...
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...
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 we were young, we were very interested in everything, especially magnets. A magnet can attract iron objects. And it also has a special property, that is, if we break a large magnet from the middle, it will become two small magnets. Each magnet has its own S pole and N pole. I don't know how many tape recorders we destroyed to play with magnets. But how did this breaking of the magnet become t...
Put the iron sheet on the fire and put the magnet on it at the same time. If the temperature of ferrite reaches 600 degrees, it will gradually lose its magnetic force. The N series of Nd-Fe-B will gradually lose its magnetic force when it exceeds 80 degrees. (Note: up to now, the best temperature resistance of strong magnetic field is 350 degrees.) Take ferrite magnet and NdFeB magnet for example....
Single-sided magnet refers to one side of the magnetic, the other side of the magnetic weak, the method is to use special treatment of galvanized iron sheet double-sided magnet wrapped, so that the magnetic side of the wrapped magnetic will be shielded, the magnetic force is refracted to the other side, the other side of the magnetic will be enhanced.Where only one side is required to be magnetic ...
We all want to choose suitable and economical high temperature resistant magnets for our own use. How can we choose the right magnets? The most important component of neodymium iron boron is rare earth neodymium (nd), and the content is also the highest. According to different brands, the content ranges from 20% - 32.5%, dysprosium and praseodymium are also important components, so the price of ma...
