The invention provides an 8-shaped coil for a transcranial magnetic stimulation contrast experiment. The coil comprises a first circular coil body and a second circular coil body, the first circular coil body is wound anticlockwise, the input end is A2, and the output end is A1; the second circular coil is wound clockwise, the input end is B1, and the output end is B2; the input ends and the output ends of the two circular coils are connected and combined through four single switches K1, K2, K3 and K4 to form different configuration states that the current directions at the intersections of the two circular coil bodies are the same or opposite; the on-off states of the single switches K1, K2, K3 and K4 are controlled through a control module. The invention further provides a configurationmanagement method of the 8-shaped coil. The 8-shaped coil is configured by controlling the on-off states of the single switches K1, K2, K3 and K4, and normal stimulation or pseudo-stimulation is freely realized. When the contrast experiment is carried out, a double-blind effect can be achieved on an operator and an experimenter.
