A bstract The electromagnetic response of anticline fold models in a uniform field has been studied using scale‐modeling. With the increasing conductance the in‐phase anomaly increases initially but then starts to decrease and finally attains a negative saturations, whilst the quadrature anomaly reaches a positive saturation. E.M. response of folds is similar to that of an interaction between two weakly coupled circuits in a dipolar field. The base of the fold is one of the characteristic parameters to determine the measured response.
