<p>PURPOSE:To provide ring core with a gap which can heighten the magnetic flux density in the gap even in the case the conditions of such as size of the core and the material to be used for it, etc., are limited. CONSTITUTION:Regarding a circular magnetic core 10 a part of which is cut to form a gap 12, the core is prepared by winding two long magnetic bodies in a plurality of times and setting the terminal parts 11c of the magnetic bodies to face each other while keeping a gap 2 between them.</p> |
