An attempt has been made to examine the role of the secondary α‐effect in the nearly symmetric dynamo. The tensor form of the effect has been found and it is concluded that this effect only plays a role under special assumption of the disturbance velocity field. The secondary alfa effect can amplify the generation of the azimuthal field from the poloidal field in the α 2 ‐dynamo rather than in the αω‐dynamo.
