1. A superconducting magnet, comprising:
magnet coils including at least one group of outer coils and at least one group of inner coils;
a container including an accommodating space;
a cooling chamber including at least one first chamber that is disposed within the accommodating space of the container and houses the at least one group of the inner coils, and at least one second chamber that is disposed within the accommodating space of the container and houses the at least one group of the outer coils;
an outer chamber that is formed based on an outer wall of the cooling chamber and an inner wall of the container;
wherein the cooling chamber is configured such that a liquid cooling medium is accommodated in the cooling chamber without flowing into the outer chamber, the liquid cooling medium being configured to cool the magnet coils to a superconducting state, the cooling chamber further including at least one third chamber disposed within the accommodating space of the container, and the at least one third chamber and the at least one second chamber being in fluid communication through a first connection passage and a second connection hole.
