Superdiamagnetism.

physics -
This effect is called meissner... Basically when something is made really cold, it becomes characterized by an absence of magnetic permeability, and the exclusion of the internal magnetic field. A phenomenon known as Superdiamagnetism. Basically the nitrogen cools the first substance to its critical temperature ( or below ) and then that substance excludes its magnetic field.
