echnical Product Description
The 70 × 15 Ring Magnet is a high-strength rare-earth permanent magnet manufactured from premium neodymium-iron-boron (NdFeB) material. Its ring-shaped geometry (with a 70 mm outer diameter and 15 mm inner hole) allows for unique magnetic field distribution and versatile mechanical mounting options in engineering designs.
This ring magnet delivers exceptional magnetic flux and pull force compared to conventional ceramic or ferrite magnets of similar size, enabling powerful holding, rotational coupling, magnetic bearings, sensor mounting, and flux guidance applications. The nickel plating provides enhanced corrosion resistance and durability, making it suitable for both indoor and protected workshop environments.
Ring magnets like this are commonly used in rotary encoders, brushless motor assemblies, magnetic couplings, generator prototypes, custom magnetic fixtures, and experimental physics setups where uniform magnetic force and geometric precision are required.
