NM4, also known as NdFeB Magnet, is a type of permanent magnet made from Neodymium, Iron and Boron. This combination of materials, when exposed to a magnetizing field, creates a powerful rare-earth magnetic field that has a number of uses in a variety of applications. This type of magnet can be used in motors, speakers, toys, medical devices, and many other applications.

NM4 magnets are extremely powerful and are usually made with a higher level of coercivity than other magnets. This means that they can maintain a strong field strength even after experiencing exposure to high temperatures, magnetization, or other forces. The increased coercivity also makes NM4 magnets more reliable in applications where frequent re-magnetization is necessary. NM4 magnets are available in a variety of sizes, shapes, and grades, making them versatile for many different applications.

One of the most common uses of the NM4 magnet is in motor applications. These magnets are used to create a very strong magnetic field that interacts with a motor’s metal parts, such as its armature, rotor, and stator. This magnetic field helps to power the motor and create a strong enough electromagnetic system to move the motor parts. The strength of the magnet greatly affects the power of the motor, making it important to choose the right grade of NM4 for the application.

NM4 magnets can also be used in applications such as speakers, to help create a powerful magnetic field. This field interacts with the metal parts inside the speaker, vibrating them in order to create sound. The power of the magnet running through the speaker affects the quality of the sound produced by the speaker, so selecting the right grade of NM4 is essential for creating a good sound.

NM4 magnets can also be used in medical applications. For example, they can be used to create magnetic resonance imaging (MRI) machines that can detect and map out internal organs and fluids. NM4 magnets can also be used in medical robots, for example to control a robotic arm placed inside a patient’s body. The power of the magnet running through the robotic arm helps it to move and manipulate in accurately and carefully to perform procedures.

NM4 magnets are also often used in toys and educational materials. These magnets can be used to help create “magLev” trains, which use the magnetic field to lift and move a train across a track. NM4 magnets can also be used to create small carts that are powered via electromagnetic fields, among many other uses in toys and other educational materials.

Overall, the NM4 magnet is an extremely powerful type of permanent magnet that has a wide range of uses in many applications. Its versatile range of sizes and grades make it a great option for a variety of applications, from motors to speakers to medical and toy applications.
