ABSTRACT:
A coil device which can accurately maintain the proportion of voltage caused by the change of the current flowing in a coil device, wherein the outside magnetic substance and the coil are fixed during an assembly of the coil device so that inside magnetic substance can be adjustably moved, or the outside magnetic substance and the inside magnetic substance are fixed so that the coil can be adjustably moved, or only the outside magnetic substance is fixed so that the coil and the inside magnetic substance can be adjustably moved therein. In addition, the coil device produces only small errors in inductance and a minimum leakage flux.
