Induction Cooker

During the infancy of induction heat treating coil development, the specific features of the induction coil primarily were determined through an analytical-, experience-, and experimental-based method. Concepts for induction coils were created by physicists. Calculations of coil parameters were determined by manually solving complex equations. Induction coil designs initially were made by draftsmen on blueprints. Most inductors were manufactured by craftsmen using a combination of copper tubing, manually machined components, and copper plates brazed together.
