About the Product

Neodymium ring magnets deliver very high flux in a compact footprint—ideal for prototype assemblies. Common uses include encoders, shaft sensing, and rotor and stator test builds, with additional applications in magnetic couplings and concentric fixtures. The inner and outer-diameter geometry simplifies precise, concentric mounting and hardware pass-through, while axial magnetization creates a clean annular field that works well with Hall and reed sensors. Select grade and magnetization to meet field strength and temperature margin requirements (standard grades operate around 80–100 °C, with high-temperature variants available). Choose coatings to match the environment, then confirm holding force with the pull-force calculator and review material data and tolerances before moving to production.

Small tube/ring magnets

They came attached in the packaging, which made aligning them very simple. I used a marker to index their alignment before detaching them. I have used them to keep access panels closed on R/C model aircraft. I plan to use them for other modeling needs (model railroading, R/C tanks, ect), a very small amount of super glue gel applied with a tooth pick to the mounting location works well. My wife has made use of them on her wall calendar/planning board as well. Thank you very much for this product; they are well made, reasonably priced, and shipping is fast. We will order all of our magnets from you. sarvis sends
