Neodymium Rare Earth Annular Magnet

BMAG Neodymium Rare Earth Annular Magnets represent the intersection of extreme magnetic power and tight geometric tolerance. The annular ring design is optimized for applications where the magnetic field must be “focused” within a specific radial gap. Using high-grade rare earth elements, these annular magnets provide a flux density that allows for the radical downsizing of sensors, actuators, and motors.

We employ a 100% magnetic flux testing protocol for BMAG rare earth annular magnets. This ensures that the magnetic field is perfectly uniform around the circumference, with no “dead zones” or spikes. The sintering process is optimized to reduce internal stresses, ensuring that the annular ring remains dimensionally stable over a wide temperature range. We also offer specialized “Passivation” treatments for magnets that will be glued into assemblies, ensuring that the adhesive bond is not compromised by surface oxidation. This is the professional’s choice for critical-path engineering.
