Alternating current electromagnetic transport measuring system

The invention discloses an alternating current electromagnetic transport measuring system. The alternating current electromagnetic transport measuring system comprises a signal generating and collecting unit, a reaction unit and a master control unit. A measured sample is arranged in the reaction unit. The reaction unit provides adjustable temperature, adjustable illumination and an adjustable magnetic field for the measured sample. The signal generating and collecting unit provides an alternating current to the measured sample. When the measured sample reacts, the signal generating and collecting unit collects the signal component, having the same phase as the alternating current, in the measured signals at the two ends of the measured sample and measures the voltage of the signal component. The master control unit controls the frequency of the alternating current of the signal generating and collecting unit, controls the temperature, the illumination and the intensity of the magnetic field of the reaction unit, collects data of the measured sample, and calculates the electromagnetic transport capacity of the measured sample. By the adoption of the alternating current electromagnetic transport measuring system, the electromagnetic transport capacity of the sample can be measured through the alternating current, and the measurement precision and the measurement efficiency are high.
