An induction heater operates by surrounding the object to be heated with a coil carrying high frequency AC current. Basically, the entire setup acts like a huge transformer with a shorted secondary.
This induction heater has a trick up its sleeve, too. Instead of using an air coil to generate heat in the cookware, this one uses an iron core instead. The project’s creator [mircemk] built an ...
A – The coil is at 0°. The coil is moving parallel to the direction of the magnetic field, so no potential difference is induced. B – The coil is at 90°. The coil is moving at 90° to the ...
