For the rapidly rotating planets with strong magnetic field and the Sun, rotation is transferred to the boundary of the magnetosphere/heliosphere and out of it. At this boundary the conductivity is high, but less than out of it. For this reason, the diffusion zone arises, where rotation is smoothly brakes down. The necessary conditions for dynamo action are analyzed in the diffusion zone. It is shown that all these con-ditions are satisfied and the energy of the damping rotation is enough for magnetic field generation there. For the Solar system this mechanism is relevant to Jupiter.
