Limitations

Cookware must be compatible with induction heating; glass and ceramics are unusable, as are solid copper or solid aluminum cookware. Although special and costly hobs are available for use with round bottom woks, with standard induction hobs, cookware must have a flat bottom since the magnetic field drops rapidly with distance from the surface. Induction rings are a metal plate that heat up a non ferrous pot by contact, but these sacrifice much of the power and efficiency of direct use of induction in a compatible cooking vessel.
