A neodymium ring magnet is a type of permanent magnet made of neodymium, iron, and boron, also known as NdFeB magnet. It is shaped like a ring with a hole in the center, allowing it to be used in a variety of applications such as sensors, motors, and magnetic bearings. Neodymium ring magnets can be found in various sizes, and their maximum operating temperature typically ranges from 80°C to 200°C.

The magnetic orientation of neodymium ring magnets refers to the direction in which the magnetic field flows through the ring. In a neodymium ring magnet, the magnetic field flows from the North pole to the South pole.
Neodymium ring magnets are available in a variety of magnetic orientations, including axially magnetized (magnetic field flows along the axis of the ring), diametrically magnetized (magnetic field flows across the diameter of the ring), and radially magnetized (magnetic field flows radially from the center of the ring to the outer surface).

Neodymium arc magnets are the strongest type of permanent magnets, making them suitable for heavy-duty applications where high magnetic force is required.
NdFeB magnets are highly resistant to demagnetization and can retain their magnetic properties for a long time.
Due to their compact size, neodymium magnets can be used in a wide range of applications, including industrial, commercial, and consumer products.
Compared to other types of strong magnets, neodymium magnets are relatively inexpensive, making them a cost-effective solution for many applications.
Neodymium magnets have a high energy density, meaning they produce a strong magnetic field in a small space. This makes them ideal for applications where space is limited.
NdFeB magnets can be small in size yet still have high magnetic strength, which makes them useful in applications where space is limited.
Neodymium magnet plating and coating can be better adapted to some harsh environments, such as ultra-low temperature, high temperature and humid environment.
