Permanent Magnet, Magna Tokyo suggests the future of new magnet.

Nd-Fe-B Bond MagnetNd-Fe-B Bond Magnet is a combined (united) magnet with extremely rapidly cooled powder of neodymium, ferrum and boron (Nd-Fe-B) by using resins. This magnet has enabled us to carry out the press working of a thin shape or a complicated shape, which traditional magnets couldn't. Since it is isotropic, it can be magnetized diametrically and axially and moreover multi poles can be magnetized, which are its characteristics.
