<p><P>PROBLEM TO BE SOLVED: To improve a magnetic circuit to have better efficiency and further smaller structure space. <P>SOLUTION: An outer core 3 has strip elements 3a and 3b with predetermined thickness D, length and width B. The outer core 3 is arranged to surround an inner core 2 so that the strip elements with the thickness D may be arranged on the end surface of the inner core 2 to be perpendicular to the X-X longitudinal direction of the inner core 2. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
