1. A magnetic resonance system, comprising:
a magnetic resonance magnet;
a storage container configured to contain the magnetic resonance magnet;
a first ramping-down device configured to ramping down the magnetic resonance magnet; and
a second ramping-down device configured to ramping down the magnetic resonance magnet, wherein a ramping down speed of the second ramping-down device is different from that of the first ramping-down device.
