A model for the dynamic magnetic field identification at the first wall of the RFX machine in presence of passive conductors

A method for the computation of the induction field in presence of open and closed passive conductors has been developed. It solves uniquely the inverse problem to determine the eddy currents needed in the passive conductors to produce a given flux. The method has been applied to the case of the RFX experimental machine to the induction field inside the vacuum vessel.
