Introduction of NdFeB Magnets Used in Teaching Stationery

    NdFeB Permanent magnet is the strongest permanent magnet. It not only has high remanence, high coercivity, high magnetic energy product, high performance price ratio and other characteristics, but also can be easily processed into various sizes. It has been widely used in craft gifts, box and stationery, bag, leather paper packaging products decorative box toy electronics. Accessories, aviation, aerospace, electronics, electroacoustics, electromechanical, instrumentation, antenna, medical technology and other equipment required for permanent magnet field, are especially suitable for the development of high-performance, miniaturized, lightweight alternative products.


The technological process of NdFeB magnets is as follows: batching smelting ingot powder making pressing sintering tempering magnetic testing grinding pinning and cutting electroplating finished products. Among them, batching is the basis, and sintering tempering is the key.


NdFeB magnet has been found to be the most commercialized magnet at present. It is called the King of Magnets. It has extremely high magnetic properties and its maximum magnetic energy product (BHmax) is more than 10 times higher than that of Ferrite. Therefore, it is also commonly known as: strong magnetism, magnetic steel, etc. Its machinability is also quite good. The working temperature can reach up to 200 degrees Celsius. Moreover, it has a hard texture, stable performance and good cost performance, so it is widely used. But because of its strong chemical activity, it must be treated on the surface.


Nissan magnet industry produces various kinds of NdFeB magnets, which have been processed into various kinds of magnet tools, such as teaching stationery magnet tools. Teaching magnet is a teaching tool mainly used for teaching experiments and demonstrations (primary school science experiment courses, middle school physics experiments). It can also be used in students'stationery, toys for children, etc. It can not only make students intuitively feel the real existence and change of magnetic field, but also vividly express its physical characteristics in concrete images, and can mobilize students' interest in learning, make them concentrate their attention and stimulate their thinking and imagination. Therefore, it is very helpful and helpful for primary and secondary school students and children to understand and recognize the magnetic field. The magnetic field is beneficial and harmless to the human body. Children can also make use of the N and S poles of the magnet to repel the same nature of the earth's magnetic field and the principle of opposite attraction to make the magnet into a compass. Can make students intuitively feel the existence of magnetic field, the nature of magnets - - same sex repellent, opposite sex attraction. Can mobilize students' learning initiative, create a good learning atmosphere, thus greatly improving the quality of teaching! Magnets can provide a constant magnetic field, is an indispensable auxiliary equipment of physical electromagnetics! In order to fully mobilize and explore children's! Create potential, develop a good inertial learning attitude that is diligent in thinking and willing to study!
