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.

Oil Filter endcap magnet

Using a ring type supermagnet to magnetize the end of your oil filter (acting to stop ferrous wear particles too small for the paper mesh to stop) is an old trick, but a good one. We use full synthetic oils that can last well over a year, but if you do not remove the iron based wear particles that can build up in the oil you can still get into trouble with longer drain intervals.
