What is the Neodymium magnet?

Neodymium magnets, also known as NdFeB magnets, with the chemical formula Nd2Fe14B, are man-made permanent magnets with the strongest magnetic force to date. Neodymium magnets are the most powerful commercial grade magnets available. Therefore, these magnets can replace many other forms of magnets in modern products, such as motors in cordless tools. Neodymium magnet is one of the most important permanent magnets. Due to its wide range of magnetic force and temperature resistance, Neodymium magnet, NdFeB has a wide application from low end market like simple attracting force to high end industrial market like servo motors and even military and aerospace market.

Advantages of neodymium magnets

Very high magnetic energy product and coercive force, high energy density, high cost performance, good mechanical properties.

Difference between neodymium magnets and ordinary magnets

The main difference is that neodymium magnets contain neodymium, iron and boron as the main chemical elements, while ordinary magnets contain iron as the main chemical element and are usually used for conventional applications. Another major difference between neodymium magnets and regular magnets is their performance. In contrast, neodymium magnets have very high remanence, coercivity and energy product, while ordinary magnets have lower remanence and energy product. However, depending on the coercivity, ferrite magnets are divided into two types: hard and soft ferrite (high and low respectively). Moreover, the Curie temperature of neodymium magnets is lower than that of ordinary magnets.

Neodymium magnets are harmful to human body, but it depends on the strength of the magnetic field, if the strength of the magnetic field does not exceed 3000, it will not affect human body in general.
