Abstract
An efficient magnetic assembly having magnetic regions is formed by applying a magnetic field from a magnetizer to predefined portions of a monolithic substrate corresponding to the magnetized regions. In the described embodiment, the magnetic field is of sufficient strength and is applied for a sufficient amount of time to magnetize the corresponding portions of the monolithic substrate. A distance between at least two adjacent magnetized regions corresponding to a neutral zone is determined and based upon the determination, the monolithic substrate is shifted an amount less than the distance corresponding to the neutral zone and the magnetic field is re-applied to at least the shifted portion of the monolithic substrate.
