Abstract :
Erroneous results can be obtained when using the integral formulation suggested in Chiampi´s paper for the computation of the electric field induced in a conductor by certain movements in a static magnetic field. Here, a complete integral formulation to describe the electric field that natural movements in and around high field MRI systems can produce in conducting objects is presented.
