A system for providing shielded dynamic shimming in a magnet assembly of a magnetic resonance imaging (MRI) scanner includes a main shim coil set located at a first radius in a gradient coil assembly of the magnet assembly. The system also includes a dynamic shim insert located at a second radius in the magnet assembly. The second radius is less than the first radius and is less than a radius of an RF coil in the magnet assembly. The main shim coil set may be operated as a shielding shim coil set for the dynamic shim insert.
