Radial Ring Magnets and Their Applications

Share This

A radial ring magnet is a magnetic component with a north and south pole on the outside diameter (OD) or inside diameter (ID). It can be used in applications where multiple or single poles are required. The radial ring magnet is one of the most versatile magnets available and can be customized to suit your needs.

Magnets are essential in technologies like wind energy, data storage, and electric vehicles. However, they can be expensive because they contain critical materials such as cobalt and rare earth elements. This drives research into alternative magnetic materials that can reduce the critical material needed.

One promising candidate is rare-earth barium copper oxide (ReBCO). ReBCO tape, which carries the currents in superconducting magnets that power fusion reactors, has a high critical temperature, allowing it to carry large currents for extended periods. ReBCO also has a low Curie temperature, which means it can be used at higher temperatures than conventional superconductor materials. Its potential to be molded into demountable magnets also improves maintenance access, simplifies materials component testing, and allows for modularity of future reactor designs.

Neodymium is a group of rare-earth metals with the highest magnetic energy density of all known permanent magnets. Neodymium magnets are often coated with nickel to protect against corrosion and oxidation. Still, other coatings can be applied to achieve other desirable properties, such as improved temperature stability or enhanced performance in specific applications.

Another popular magnet is samarium cobalt, which can be found in many different grades to meet various application requirements. Samarium cobalt is typically fabricated into discs, blocks, rings, and arc segments in standard sizes, but it can also be custom-fabricated to blueprint specifications. Like neodymium, samarium cobalt is often coated to protect against corrosion and oxidation.

Both neodymium and samarium cobalt have a high resistance to demagnetization, making them suitable for use in various applications. In the aerospace industry, where every ounce counts, neodymium radial ring magnets play a crucial role in the delicate dance of flight control systems. From ensuring avionic sensors’ accuracy to enhancing control surfaces’ responsiveness, neodymium radial rings help pilots safely and efficiently navigate the skies.
