Ring neodymium magnets, also known as neodymium ring magnets or neodymium disc magnets with a center hole, are a specialized form of neodymium magnet featuring a circular shape with a hole in the center. This design offers unique advantages for specific applications where mounting or assembly requirements dictate the need for a centralized void.
Ring Neodymium magnet mainly has three types of magnetization directions, axial, diametrical and radial magnetization. Axial magnetization is easy to understand, and the magnetic lines travel through the length of the magnet. Diametrical magnetization means magnetic lines through wall thickness diametrically. Radial magnetization means magnetic lines from the circle center to the OD surface radially.
Ring neodymium magnets are widely used in industries such as electric motors, medical, sensors, and speakers, automotive, aerospace, and power generation applications. Due to the magnetic properties of rare earth magnets, it has replaced other magnetic materials to enable smaller designs but achieve the same results. These Shaped Ring Neodymium Magnets are widely used in engineering, manufacturing, and various consumer products, including loudspeakers, magnetic bearings, magnetic couplings, magnetic hooks, and magnetic sensors. The ring shape provides a concentrated magnetic field around the perimeter while allowing for easy mounting through the central aperture, facilitating efficient and space-saving integration into diverse systems. Ring neodymium magnets are valued for their exceptional magnetic strength, compact design, and versatility, making them indispensable in numerous industrial and commercial applications requiring precise magnetic control and performance.
NdFeB rods and cylindrical magnets are commonly used in power generation equipment.
