The invention discloses a maglev train electromagnet current detection circuit and a maglev train. The circuit comprises a forward circuit, a reverse circuit and a comparison circuit, wherein the forward circuit is used for performing positive value taking processing on an input first analog signal and outputting a first signal; and the reverse circuit is used for carrying out negation processing on an input second analog signal and outputting a second signal. The first analog signal is an electromagnet input current and the second analog signal is an electromagnet output current, or the first analog signal is the electromagnet output current and the second analog signal is the electromagnet input current. And the comparison circuit is used for determining that the electromagnet input current and the electromagnet output current are normal when the sum of the first signal and the second signal is within a preset signal threshold range. Through the detection mode of a hardware circuit, whether the input current and the output current of the magnetically levitated train electromagnet are consistent can be accurately detected, and then whether the electromagnet current is reliable is determined.
