Electromagnetic coil assemblies having braided lead wires and methods for the manufacture thereof

An electromagnetic coil assembly, comprising:

• a coiled magnet wire;
• a rigid body of inorganic dielectric material surrounding the coiled magnet wire;
• a braided lead wire having an end portion joined to the coiled magnet wire within the rigid body of inorganic dielectric material, the braided lead wire projecting from the body of dielectric material to provide an electrical connection to the coiled magnet wire;
• and
• an electrically-insulative cloth wrapped at least partially around the coiled magnet wire and over the end portion of the braided lead wire joined to the coiled magnet wire.

A method for manufacturing an electromagnetic coil assembly, comprising:

• winding a magnet wire around a support structure to produce an electromagnetic coil;
• creating a joint between the magnet wire and a braided lead wire;
• and
• forming a body of dielectric material around the electromagnetic coil in which the joint is at least partially embedded.
