Richie Burnett has a Induction Heating Demonstration that is worth having a look at. Richie has also done extensive work with Tesla coils, make sure you have a look at those also.

“Induction heating is a non-contact heating process. It uses high frequency electricity to heat materials that are electrically conductive. Since it is non-contact, the heating process does not contaminate the material being heated. It is also very efficient since the heat is actually generated inside the workpiece. This can be contrasted with other heating methods where heat is generated in a flame or heating element, which is then applied to the workpiece. For these reasons Induction Heating lends itself to some unique applications in industry.

How does Induction Heating work ?

A source of high frequency electricity is used to drive a large alternating current through a coil. This coil is known as the work coil. See the picture opposite. The passage of current through this coil generates a very intense and rapidly changing magnetic field in the space within the work coil. The workpiece to be heated is placed within this intense alternating magnetic field.”
