Abstract: A magnetic field freshness-preserving storage container and a refrigerator. The magnetic field freshness-preserving storage container includes a storage box, two uniform magnetization plates, and two sets of electromagnetic components. Each set of electromagnetic components is arranged corresponding to one uniform magnetization plate and forms an electromagnetic field after being electrified. The magnetic field distribution of the electromagnetic field can be changed by means of the uniform magnetization plates, such that the electromagnetic field is distributed more uniformly in the storage space. Since the electromagnetic field is distributed more uniformly in the storage space, stored objects can have the same storage quality. In addition, the uniform magnetization plates can save on the consumption of magnetic materials.
