A method and apparatus for magnetic field drift compensation for a superconducting magnet system includes electrically coupling a micro-flux injection system to a secondary B<SUB>0 </SUB>superconducting coil in a secondary compensation circuit; magnetically coupling the secondary compensation circuit to the superconducting magnet via the secondary B<SUB>0 </SUB>superconducting coil; switching the micro-flux injection system on and off either thermally or magnetically to induce a first current from a flux coil of the secondary compensation circuit into the secondary B<SUB>0 </SUB>superconducting coil producing a secondary field to compensate magnet field drift of the superconducting magnet.
