A very large part of the advancement and development of modern society is undeniably attributed to the discovery and cultivation of electricity. Industry utilizes the phenomenon that is electricity in modern day applications through a variety of methods. One of the most impressive such applications of electricity, are those which occur during heat induction technology.

Physical and compositional changes can be made to an electrically conductive material, such as Silver, Copper, Gold, Aluminum, Nickel, Zinc, Brass, Iron, Tin, Phosphor Bronze, Lead, Steel, ionic polymers, and graphite, by creating an oscillating electric-magnetic field around the material. In most instances the process begins with a solid AC current which is sent throughout an inductor, such as a copper coil. The conductive piece to be heated is then placed within, or pushed through, the inductive coil which interrupts the once solid AC current by becoming a short circuit minor. This induces a flow of currents which move against the electrical resistivity of the piece known as eddy currents. Known as the Joule Effect, the antagonistic flow of eddy currents generates heat within the piece being treated. Further heat may be induced by means of magnetic friction which occurs as a piece passes through the magnetic field created by the coil; this process is referred to as, hysteresis. The result of these heating procedures is the creation of an environment where the treatable piece can be melted, cured, tempered, annealed, hardened, forged, bent, brazed, shrunk, or even perpetually generated!

It is easy to see that this technology provides mankind with the ability to create! The most remarkable feature of heat induction technology is that the entire heating process occurs without any direct heat source or contact to the treated piece. This expands the possibilities to use this technology in flammable environments, under water, or even in a complete vacuum. Because of its flexibility and diverse applications, heat induction technology is a cost-effective and beneficial production procedure.
