Using traditional methods, a fine magnetic pole pitch of less than 1 mm was very difficult to achieve and a complicated magnetization system was required. A linear wire circuit pattern was designed and formed on the printed circuit board (PCB) with a periodic structure, which provides a loop allowing the current to flow in opposite directions to induce different magnetic fields among the wire circuit. Correspondingly, a multi‐pole magnetic component with a fine magnetic pole pitch of less than 1 mm was accomplished. Various multi‐pole magnetic components with different pitch sizes of 400 μm and 500 μm were fabricated to investigate the field variation. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
