ABSTRACT:
A cylindrical superconducting solenoid adapted to receive cylindrical inserts within the bore thereof. The inserts are selected having a permeability or radial thickness which will absorb or conduct a portion of the magnetic field within the interior bore of the cylindrical solenoid. Thereby, the interior magnetic field can be adjusted to any predetermined value without changing the total amount of trapped flux within the superconducting solenoid.
