An induction furnace is disclosed comprising a crucible for holding a material to be heated by the furnace, an induction coil assembly, and a module-support assembly surrounding and radially supporting the induction coil assembly so as to facilitate the replacement and reconnection of the induction coil assembly. The induction coil assembly comprises an induction coil, an upper yoke, a lower yoke, and a plurality of intermediate yokes that are spaced apart from each other. The induction coil is wound around the crucible and defines the periphery of the induction furnace. The intermediate yokes are arranged to extend around substantially all of the periphery defined by the wound induction coil. The upper and lower yokes are electromagnetically coupled together by the plurality of intermediate yokes. The module-support assembly has upright members and shaft members that allow each of the plurality of intermediate yokes to be separately removed from the furnace while the other intermediate yokes remain in place and to allow for the induction coil assembly to be removed from the furnace in its entirety.
