The Strongest Permanent Magnet - Neodymium Magnet

Neodymium magnet is a general term for the powerful magnet. Its chemical formula is Nd2Fe14B. The neodymium magnet is a kind of artificial permanent magnet. So far, it is the strongest permanent magnet. The Strongest Permanent Magnet The Strongest Permanent Magnet

At present, the most commercially available magnet, known as the magnet king, has very high magnetic properties and its maximum magnetic energy product (BHmax) is more than 10 times higher than that of ferrite. NdFeB magnet is a tetragonal crystal formed by neodymium, iron, and boron (Nd2Fe14B). It is not expected that in the next 20 years, magnetic materials will replace neodymium iron boron magnets. The main materials for producing Nd-Fe-B magnets are neodymium, praseodymium, pure iron, aluminum, ferroboron, and other rare earth materials.

What is the working principle of strong magnetism?

Each magnet has two poles. The position of the pole represents the strongest magnetic force. These two poles are called N and S respectively. According to magnetism recovery experts, under the influence of the Earth, a magnet that can rotate freely will naturally point north at one end and South at the other. The naming of magnetic poles comes from this. When a magnet is divided into two or more parts, each part becomes a new magnet - that is, it has two poles. Heterosexual poles attract, and isotropic poles repel. When the N poles of two magnets are put together, the two magnets repel each other - that is, they move in the opposite direction. The same is true for putting S poles of different magnets together. When the N pole of one magnet is placed close to the S pole of the other, the two magnets are strongly attracted to each other and move closer to each other. When the magnets are far apart, they do not necessarily produce repulsive or attractive magnetic reflections, because the magnetic force has a certain distance limitation. The range of magnetic forces can be called a magnetic field. The closer to the magnet, the stronger the magnetic force; the farther away from the magnet, the weaker the magnetic force. The magnetic field range is generally represented by a series of lines, called magnetic lines, extending from the N pole of a magnet to the S pole of the same magnet or another magnet. A strong magnet can attract objects made of iron, steel, cobalt, or some other magnetic materials. Under the action of magnets, objects made up of magnetic materials can also become magnets themselves. The magnet attracts these objects because a magnetic pole of the magnet magnetizes the end of the object into a magnetic pole different from that of the magnet and then attracts each other. For example, the N of the magnet will magnetize the nearest part of the object to the S pole. At this point, the other end of the object will become the N pole.
