What Is Neodymium Magnet

  Magnets can be divided into "permanent magnets" and "non-permanent magnets". Permanent magnets can be natural products, also known as lodestones, or artificially made (the strongest magnets are neodymium magnets). Rather than permanent magnets, they are only magnetic under certain conditions, usually in the form of electromagnets, which use an electric current to strengthen their magnetic field.

  Magnets are magnetic and can attract iron objects; magnets have magnetic poles, and each magnet has two magnetic poles, the N pole and S pole, which exist in pairs: when two magnets are close to each other, the same magnetic poles will repel each other and push Open, different magnetic poles will attract and stick to each other. That is, the same poles repel each other, and opposite poles attract each other.

  The composition of magnets is iron, cobalt, nickel and other atoms, the internal structure of its atoms is relatively special, and it has a magnetic moment itself. Magnets can generate magnetic fields and have the property of attracting ferromagnetic substances such as iron, nickel, cobalt, and other metals. The midpoint of the bar magnet is suspended by a thin wire. When it is stationary, its two ends will point to the south and north of the earth. The end pointing to the north is called the north pole or N pole, and the end pointing to the south is the guide pole or S. pole.

  NdFeB magnets are the magnets with the highest commercial performance found at present. They are called the magnet king. They have extremely high magnetic properties and their maximum magnetic energy product (BHmax) is more than 10 times higher than that of ferrite. Its own machinability is also quite good. Operating temperature up to 200 degrees Celsius. Moreover, its texture is hard, its performance is stable, and it has a good price/performance ratio, so it is widely used. But because of its strong chemical activity, its surface layer must be treated.

  Ningbo MGT Magnetism Co., Ltd is a Strong Neodymium Magnet Manufacturer, its main products are Disc Neodymium Magnet, etc. Welcome to consult!
