Are there any true radial ring magnets?

Radial NdFeB ring magnets are a special type of rare-earth magnet whose magnetic field is distributed radially to form a continuous and uniform magnetic field. Unlike traditional axially magnetized ring magnets, the magnetic field lines of radial magnets extend along the radius of the cylinder or sphere. This unique magnetization method makes it excel in applications that require high precision and high efficiency.

What is a radial magnetic field?

A radial magnetic field refers to a magnetic field where the magnetic field lines radiate along the radius of a cylinder or sphere. This magnetic field is not formed by simply placing the north and south poles of the magnets relative to each other, but relies on advanced magnetization processes and dedicated equipment. The uniformity and stability of the radial magnetic field give it significant advantages in rotating systems and dynamic applications, and can reduce performance fluctuations caused by uneven magnetic field distribution.

Differences between radial magnets and traditional magnets

Traditional axially magnetized ring magnets usually have a vertical (along the axis) or horizontal (along the diameter) magnetic field direction, which may cause uneven magnetic field distribution in rotating systems, leading to torque fluctuations or efficiency losses. The magnetic field of radial magnets is distributed radially, providing a smoother magnetic flux, ensuring that the system remains stable when operating at high speed or high precision.
