A method for manufacturing an electromagnetic coil assembly, comprising: providing a braided aluminum lead wire (36, 38, 140) having a first end portion and a second end portion; and joining the second end portion of the braided aluminum lead wire (36, 38, 140) to a coiled magnet wire; characterized in that the method further comprises: prior to joining the second end portion of the braided aluminum lead wire to the coiled magnet wire, brazing the first end portion of the braided aluminum lead wire to an electrically-conductive interconnect member (104, 106, 142); and after joining the second end portion of the braided aluminum lead wire to the coiled magnet wire, forming an inorganic dielectric body around the coiled magnet wire such that (i) a joint, formed between the second end portion of the braided aluminum lead wire and the coiled magnet wire, including the second end portion is buried within the inorganic dielectric body, and (ii) the braided aluminum lead wire extends with its second end portion into the inorganic dielectric body, and to the coiled magnet wire to provide the joint, forming an electrical connection between the electrically-conductive interconnect member and the coiled magnet wire, being embedded in the inorganic dielectric body. providing a braided aluminum lead wire (36, 38, 140) having a first end portion and a second end portion; and joining the second end portion of the braided aluminum lead wire (36, 38, 140) to a coiled magnet wire; characterized in that the method further comprises: prior to joining the second end portion of the braided aluminum lead wire to the coiled magnet wire, brazing the first end portion of the braided aluminum lead wire to an electrically-conductive interconnect member (104, 106, 142); and after joining the second end portion of the braided aluminum lead wire to the coiled magnet wire, forming an inorganic dielectric body around the coiled magnet wire such that (i) a joint, formed between the second end portion of the braided aluminum lead wire and the coiled magnet wire, including the second end portion is buried within the inorganic dielectric body, and (ii) the braided aluminum lead wire extends with its second end portion into the inorganic dielectric body, and to the coiled magnet wire to provide the joint, forming an electrical connection between the electrically-conductive interconnect member and the coiled magnet wire, being embedded in the inorganic dielectric body. prior to joining the second end portion of the braided aluminum lead wire to the coiled magnet wire, brazing the first end portion of the braided aluminum lead wire to an electrically-conductive interconnect member (104, 106, 142); and after joining the second end portion of the braided aluminum lead wire to the coiled magnet wire, forming an inorganic dielectric body around the coiled magnet wire such that (i) a joint, formed between the second end portion of the braided aluminum lead wire and the coiled magnet wire, including the second end portion is buried within the inorganic dielectric body, and (ii) the braided aluminum lead wire extends with its second end portion into the inorganic dielectric body, and to the coiled magnet wire to provide the joint, forming an electrical connection between the electrically-conductive interconnect member and the coiled magnet wire, being embedded in the inorganic dielectric body.
