Surface chemistry using an induction heater

WebSurface Chemistry has a major role in various chemical processes such as: Enzymatic reactions at the biological interfaces found in the cell walls and membranes. In the … WebIf we apply a continuously changing current to a coil of wire, we will have a continuously changing magnetic field within it. At higher frequencies the induction effect is quite strong and will tend to concentrate on the surface of the material being heated due to the skin effect. Typical induction heaters use frequencies from 10kHz to 1MHz.
