Induction Hob
The induction coil already published makes a changing magnetic field, and the induction motor uses one to drive currents in a rotor. The cooking rung uses the same trick to heat the pan itself: no element, no flame, and a cold top - the pan is the only thing that gets hot.
**US 4,169,222**, "Induction cook-top system and control", Raymond M. Tucker, assigned to Rangaire, filed 26. July 1977, granted 25. September 1979: mains rectified to DC, switched into induction heating coils under a non-metallic top, with the power set by the switching.
**A mains hob is never opened or built here.** You build a LOW-VOLTAGE induction heater from a 12–24 V module and measure which metals it can heat - which is exactly why some pans work on a hob and others do nothing.

Bolt the coil to the ZVS module's terminals. Set the bench supply to 12 V with a 5 A limit; the module draws several amps and its transistors get hot. Never run it with no metal near the coil for more than a few seconds, and keep the supply under 24 V.

History & Context
History & Context
**What the patent specifies:** a cook-top with rectifier, gated semiconductor switches and induction heating coils beneath a non-metallic top, with the heat set by how the coils are switched. **Modern build (derived):** a low-voltage ZVS heater and metal discs.
Induction reached kitchens slowly because the electronics were dear; efficiency into the pan is high and the top stays cool enough not to burn spills on. Its limits: the pan must be magnetic (so much old aluminium and copper cookware is useless), the electronics whine, and a pan smaller than the coil couples poorly.
