Abstract In order to reduce the electric current loss and the heat release in a shielding coil, partially shielding coils 1Zts and 1Zbs are employed having their windings positioned corresponding only to a high winding density zone 1Zp, rather than corresponding to the entire winding area, of main gradient coils 1Zt and 1Zb.
