AbstractWe report the development of a magnetically driven Persistent Current Switch operated in a dilution refrigerator. We show that it can be safely used to charge a 60mH coil with 0.5A at 11mK, which heats up the dilution refrigerator to 60.5mK. Measurements at 4K on a 440μH coil reveal a residual resistance of R⩽3.3pΩ
