This is a series of interactive lecture demonstrations with a theme of induction and Faraday's law, typically presented with a series of iClicker questions. Students predict the direction of current ...

How efficiently and effectively a workpiece is heated is determined by the induction coil. Induction coils are water-cooled copper conductors created from copper tubing which is readily formed into ...

THE discovery of the Röntgen rays has created a revived interest in many of the beautiful experiments that can be performed with the aid of the Ruhmkorff induction coil, and is thus indirectly a ...

Induction heating is an accurate, fast, repeatable, efficient, non-contact technique for heating metals or any other electrically-conductive materials. An induction heating system consists of an ...
