              The working theory of magnet comes from electromagnetic induction. Without magnets, today&#39;s technological development will not be improved at all. In the previous industrial era, the existence of magnets did alleviate the sources of man...
              Although the magnet is not a very important material for us, but do not underestimate its use and application range. The material of magnet must be known by all of us. We will not introduce it in detail here. Magnets are widely used in many...
              Permanent magnet synchronous motors rarely use two poles? Why is that? The professional questions will be handed to the professionals for answers. Bei Ke magic has sorted out the answers from several electrical engineers, hoping to help you...
              Under the condition of ordinary plate or rolling plate, if it is not processed deeply, it will not be attracted by the magnet. However, if it is stretched deeply, there is a local martensitic structure in 304, showing tiny magnetism, it may...
              1. The magnetic properties of NdFeB magnets are very strong. You should first avoid holding hands or other parts of your body with magnets. For large size and strong magnetism, you need to pay more attention to safety. 2. Do not connect a s...
              Magnets sound very familiar. Badge Magnets also very common in our real life. Magnets can absorb iron. Many people have used them, but when asked about the specific application of magnets in daily life, it is difficult to generalize. What ...
              Magnets have no effect on temperature reduction and are sensitive to temperature rise. Each magnet has its own maximum temperature. For example, the maximum working temperature of ferrite magnet is 300 ℃, and the maximum working temperatur...
              In the process of our use, demagnetization is also very normal, because some external factors and some self factors are likely to cause demagnetization, so let&#39;s understand why the demagnetization of NdFeB magnet occurs in high temperat...
              The frequency of using magnets is still relatively high. I don&#39;t know if you have any bubbling phenomenon, because in life, we are not working, there are many problems we may not be able to meet. After the foaming of magnets, it will de...
              For the detection of some special purpose steel metal products, we need to consider the detection of its magnetic properties first. For example, various silicon steel sheets (soft magnetic materials), permanent magnets (hard magnetic materi...
              We all know that it is a solid sintered from rare earth Nd-Fe-B. Its magnetism is very strong and it is used in many fields. It is also a common magnet with large market demand. It has different shapes and sizes, thick and thin, long and sh...
              During our work, we will definitely choose to treat every step strictly. If there is a problem, it will certainly appear in our later use process. Then let&#39;s learn how to choose coating for iron boron magnet? The appropriate coating sha...
              Storage is a very important thing, for example, if one of our clothes is not placed properly, it will be very easy to get wet, or be bitten by rats and insects, which are caused by not storing well. Not to mention other products, it will al...
              (1) Fill in antifreeze. Antifreeze can be used when the temperature is too low and conditions permit. The cooling system shall be thoroughly cleaned before use, and the antifreeze with good quality and low corrosiveness shall be selected to...
              Ferrite tile is widely used in kitchen small household electrical appliances motor, treadmill motor, air pump, toy motor, vacuum pump motor, car window motor, servo motor, etcWhy ferrite tile material? Mainly because of the low price, it is...
              Some magnets with complex shapes are called special-shaped magnets for short. Because of the difficulties in production and processing, not every manufacturer does this. Dongguan carrich magnet factory is a professional manufacturer of spec...
