PURPOSE:To facilitate the formation of a multiplex-winding coil on a magnetic core, by arranging a plurality of bobbins each wound with a coil to be mounted on the same magnetic core and the coils are connected sequentially. CONSTITUTION:A core 1 is made of a high-conductivity material in a cylindrical rod and five bobbins 2-6 are provided thereon 1. The bobbins 2-6 are wound with coils 7-11, which are connected in series in the order of number, in such a manner that the addition of the number of turns of each of the coil 7-11 shall be the required total number in the turns of all coils. The necessary connection between the coils enables the formation of a magnetic detector as a whole. Thus, the same function can be obtained with the conventional single-multiplex- winding coil.
