A superconducting magnet assembly comprises a superconducting magnet ( ) which, under working conditions, generates a magnetic field in a working volume, the superconducting magnet being connected in parallel with a superconducting switch ( ), the switch and magnet being adapted to be connected in parallel to a power source ( ) whereby under working conditions with the switch ( ) open, the magnet ( ) can be energised by the power source to generate a desired magnetic field in the working volume following which the switch ( ) is closed, characterised in that the assembly further comprises a resistor ( ) connected in series with the switch ( ), the resistor ( ) and switch ( ) being connected in parallel to each of the magnet ( ) and the power source ( ).
