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.

A heating/stirring cooker includes a stirring body. The stirring body is detachably attached to the interior of a container, and stirs the food. The stirring body includes a blade, a permanent magnet, a magnetic metal plate, a storage, and a clutch. The blade stirs the food. When the stirring body is attached to the container, the permanent magnet is located opposite the inner bottom surface of the container and receives a rotating magnetic field. The magnetic metal plate is provided on the permanent magnet and inhibits magnetic flux leakage. The storage has a perimeter on which the blade is formed, and movably stores the permanent magnet. The clutch transmits the rotational force of the rotating magnetic field to the storage, only when a claw is in engagement with a notch. The stirring body generates high rotational force when attached and suppresses the impact of the magnetic field when detached.
