Abstract
The present invention relates to a system (100) for creating a magnetic field via a superconducting magnet (102) intended to produce said magnetic field. The system (100) according to the invention comprises a first branch including the superconducting magnet (102) formed by a coil inductance (L′) in series with a residual resistance (R′2), a second branch comprising a protection resistance (R′3) and a third branch comprising a power source (103). Furthermore, the system comprises a fourth branch formed by a resistance (R′1) mounted in series with a current-limiting superconducting device (106) switching from a low-resistance state to a high-resistance state when the current passing therethrough exceeds a breaking current, said first, second, third and fourth branches being mounted in parallel.
