ABSTRACT:
The present invention is comprised of an outside magnetic substance forming an endless loop, an inside magnetic substance formed inside of said outside magnetic substance and coil wound on the periphery of said inside magnetic substance. In a coil device of the present invention with gaps between both ends of said outside magnetic substance and said inside magnetic substance, notches or holes are provided in said outside magnetic substance for the purpose of inserting insert a jig therein so as to adjustably move the position of said inside magnetic substance, wherein said notches or holes correspond to the gaps provided in both ends of said inside magnetic substance. In said coil device, the inside magnetic substance can be adjusted and moved its position by pressing a bar-like jig through the notches or the holes provided in the outside magnetic substance. Thus, it has become possible to adjust the value of the inductance by about 25% experimentally.
