Neodymium ring magnets is one basic shape of Rare earth magnets and perment magnets its usually made via grinding ourter diameter of semi-finished cylinders to get a appropriate tolerance disc and then cut the ring magnets to the suitable size next mill the two furfaces and finally do coating/plating to keep from rusting.
