1. A magnetic apparatus, comprising;
a plurality of ferromagnetic plates, each ferromagnetic plate includes a concave end for mounting on a curved ferromagnetic surface;
a plurality of magnets being configured in an alternating arrangement with the ferromagnetic plates,
wherein each magnet is positioned between a pair of the ferromagnetic plates,
wherein the magnets are oriented so that like magnetic poles of the magnets oppose each other, and
wherein each magnet is sized such that the magnet does not contact the curved ferromagnetic surface; and
an assembly for joining the ferromagnetic plates and magnets together so that each magnet firmly abuts said pair of the ferromagnetic plates thereby allowing the ferromagnetic plates to become magnetically saturated.
