The modern origin of electromagnetic wire originated in a small building south of Swinney Park. Insulated copper or aluminum wire was wound in a coil to generate an electromagnetic field. Developed in Fort Wayne, Fort Wayne was awarded 
the "World Magnet Wire" The title of "Du".

Magnet wire is an insulated electrical conductor, most commonly copper or aluminum, which generates an electric field when it is wound into a coil and energized. Ninety percent of the electrical energy needs to be modified through the 
use of magnets to be useful. From high-voltage transformers to mobile phones, enameled wires are everywhere.

Magnet wires are metallic conductors insulated with varnish, usually used in electrical applications. In most cases, it is wound in coils of different shapes to generate magnetic force for motors, transformers, magnets, etc.
