Large size ferrite ring

220mm large ring magnet OD220 x ID110 x T20/25 mm

This is a relatively large ring magnet, made of sintered ferrite, with an outer diameter of 220mm, a middle hole of 110mm and a thickness of 20mm. Compared with neodymium magnets, it has a high cost performance ratio and greater scope of work. It can be used in experiments, industry, mechanical equipment, electroacoustics and other fields....
