A method for controlling an induction coil on an induction hob involves a power generation for a primary power on the induction coil for power transmission to an electrical consumer put onto a cover above the induction coil, which consumer has a receiver coil and an electrical load connected thereto, being adjusted. The induction coil forms a primary-side resonant circuit with a capacitance connected in series, and the induction coil and the receiver coil are coupled in the style of a transformer such that a current in the induction coil induces a voltage in the receiver coil with a flow of current and generation of the secondary power in the load of the electrical consumer. The control means can attempt to adjust the desired secondary power to a steady state using maximum modulation of the voltage effectively applied to the primary-side resonant circuit, as second manipulated variable. The primary power is decreased in a first step by virtue of the voltage effectively applied to the primary-side resonant circuit, as second manipulated variable, being decreased before the operating frequency as first manipulated variable is increased in a second, subsequent step.
