Magnet assemblies and methods for making the same

A superconducting magnet assembly, comprising:

• a superconducting magnet configured to generate a static magnetic field;
• an iron shield configured to shield the superconducting magnet;
• a magnetic gradient coil assembly configured to generate a gradient magnetic field;
• a plurality of magnetic lamination elements disposed on the iron shield;
• and
• one or more non-magnetic gaps defined between adjacent magnetic lamination elements along a direction of the static magnetic field generated by the superconducting magnet.

A method, comprising:

• providing a superconducting magnet configured to generate a static magnetic field;
• providing an iron shield configured to shield the superconducting magnet;
• providing a magnetic gradient coil assembly configured to generate a gradient magnetic field;
• and
• providing one or more magnetic lamination elements disposed on the iron shield to reduce eddy current induced by the gradient magnetic field in the iron shield.
