In an electrical appliance, a thermal conductor includes a hollow heat-conducting member that has inner and outer walls confining an enclosed chamber therebetween, and a superconductor disposed in the chamber. A heat-insulating layer is provided on an outer peripheral surface of the outer wall. A temperature control device includes a thermoelectric unit disposed on and in thermal communication with the outer wall of the heat-conducting member. A control unit is connected to the thermoelectric unit and is operable so as to enable the thermoelectric unit to operate in either a heat-absorbing mode, where the thermoelectric unit absorbs heat from the thermal conductor so as to reduce temperature in the heat-conducting member, or a heat-radiating mode, where the thermoelectric unit radiates heat to the thermal conductor. A power source is connected to the temperature control device for supplying electric power thereto.

The electromagnetic coil assembly of claim 1, wherein a second pair of projection portions, a third projection portion and a fourth projection portion, each having a hook-shaped cross-section, are disposed on said first end surface of said bobbin, such that said third projection portion retains said electrical wire adjacent to said first connecting member and said fourth projection portion retains said third lead wire adjacent to said second connecting member. 3. The electromagnetic coil assembly of claim 1, wherein said starting end portion of said first lead wire and said electrical wire adjacent to said first connecting member overlap and are secured to said first projection portion and said third projection portion, respectively, and wherein said starting end portion of said second lead wire and said third lead wire adjacent to said second connecting member overlap and are secured to said second projection portion and said fourth projection portion, respectively. 4. The electromagnetic coil assembly of claim 1, wherein said first pair of projection portions are integrally molded with said first end surface of said bobbin, and have a cross-sectional thickness which gradually increases towards its base. 5. The electromagnetic coil assembly of claim 2, wherein said second pair of projection portions are integrally molded with said first end surface of said bobbin, and have a cross-sectional thickness which gradually increases towards its base. 6. The electromagnetic coil assembly of claim 1, wherein said first pair of projection portions are integrally molded with said first end surface of said bobbin, and have engagement portions to said first and second lead wires the heights of which gradually decreases from said first end surface to inner parts of said engagement portions. 7. The electromagnetic coil assembly of claim 2, wherein said second pair of projection portions are integrally molded with said first end surface of said bobbin, and have engagement portions to said electrical wire and said third lead wire the heights of which gradually decreases from said first end surface to inner part of said engagement portions.
