Hope supplies Ring Magnets made from both strong rare earth Neodymium materials and more economical Ferrite material. Our range includes large-diameter magnetic rings up to 145 mm wide and small magnetic rings with diameters as small as 5mm. The inside diameter across the void area of each ring magnet can also vary to make the ring magnet more suited to specific applications or for more suitable fitment options. There is also the direction of magnetism options available which means the magnetic rings can be manufactured as an axial ring magnet, a radial ring magnet or a diametrically magnetised ring magnet. The direction of magnetism may be more suitable for special manufacturing operations or specific applications in consumer electronic goods. As with other magnet shapes, the vast majority of ring-shaped magnets are axially magnetised, meaning the poles lie at each end of the height dimension i.e. thickness.
