Common Post-processing Methods for Sintered NdFeB Magnet Sintered NdFeB is prepared by powder metallurgy. The material has high hardness, high brittleness, and is easy to break; and the heat release, corrosion and defects in the processing process will cause damage to the magnetic properties. Therefore, it is necessary to choose a suitable processing method according [...]
Physical Properties of Sintered NdFeB Magnet As the core functional component, sintered NdFeB permanent magnets are widely used in instruments and equipment such as motors, electroacoustics, magnets and sensors. During the service process, the magnet will be subjected to environmental factors such as mechanical force, cold and heat changes, alternating electromagnetic field, etc. If environmental [...]
Radiation Magnetic Ring At present, most of the mainstream permanent magnet brushless motors use surface-mounted or embedded magnetic tiles to form a ring-shaped magnetic circuit. However, the splicing magnetic ring has the disadvantages of high processing precision of magnetic tiles, high assembly difficulty, poor stability of magnetic pole transition, and serious motor noise, and the [...]
The Ingredients and Effects of Sintered Neodymium Iron Boron We all know that the main raw materials of sintered NdFeB permanent magnets are three elements: neodymium, iron and boron, but in addition, many other elements will be added to the raw materials, and these elements play different roles in the magnet. , Manufacturers often make [...]
Is Absorption of the Same Performance and Volume Magnet? Many friends may have such a question, the same performance and volume magnet, do they suck the same? It is said on the Internet that the suction power of the iron boron boron is 640 times the weight of its own weight. Is this credible? This [...]
Neodymium Magnet in 3C Consumer Electronics Products 3C consumer electronics mainly include six categories: mobile phones, tablets, laptops, watches, headphones, and wireless charging devices. Take Apple products as an example, iPhone, iPad, Mac, Watch, AirPods, MagsaFepParts. Where can I use neodymium iron boron magnets in these products? What is the principle of use? What are [...]
Magnets in Permanent Magnet Motor The largest application area of rare earth permanent magnet is permanent magnet motor, commonly known as motor motor. In the broad sense, motors include electric motors that convert electric energy into mechanical energy and transform mechanical energy into electrical energy. The law of electromagnetic induction or the law of electromagnetic [...]
Bar Magnet Heating Will Lose Magnetism, Why Does High-temperature Liquefied Iron Nucleus Produce a Huge Magnetic Field? The atoms in the magnet are arranged neatly in accordance with certain rules, which is why magnets have magnetic reasons. When heating the magnet, the arrangement of the atom is disrupted and the magnetic is reduced. When heating [...]
Experimental Detection Magnetic Material Remember the best way to remember the above three types of magnetic materials is to distinguish between iron magnets and other types of magnets. The iron magnet is permanent, while the rest is not. The difference between cigarette magnetic materials and antimagnetic materials is that the magnetic material is attracted by [...]
Three Forms of Magneticity So why not everything is magnetic? In fact, everything is magnetic. Because moving electrons produce magnetic fields, and everything is composed of electrons, everything must be magnetic. However, some materials show stronger magnetism, while others show very weak magnetism. why is that? Q1, iron magnetic We have already talked about the [...]
What is Magnetic You still remember that when you were a kid, you removed the audio at home and picked up a large piece of magnet from it. You were excited to hold the magnet to suck various iron products. Anything that could be magnetized was spared. During this period, a profound truth was produced [...]
The sixth sense of magnetism is first confirmed That Human Beings Can Feel Magnetic Field and Maybe Predict The Future! In our real life, there are often strange experiences, and sometimes I always feel that my crow's mouth is said. There is always a feeling of feeling that something is going on, but I did [...]
