Custom Neodymium Ring Magnet for Motor and Speaker
depictio producti
Neodymium est metallum ductile et malleabile argenteo albo.Neodymium valde paramagneticum est.Maior applicatio neodymii est in vi magnetum permanentium altarum secundum Nd2Fe14B, quae in motoribus electricis et generantibus magno opere adhibitis, tum in magnetibus fusis computatoribus duris agitationibus et turbines ventorum adhibitis.Magnetes neodymium in amplis figuris, magnitudinibus et gradibus praesto sunt. Magnetes ringi sunt sicut orbes vel cylindri, sed cum centro foraminis.
