The invention discloses superconducting weak magnetic field compensation equipment. The superconducting weak magnetic field compensation equipment comprises a superconducting cylinder (1), a top cover(2), a rotary shaft (4), a rotation speed control system (5) and a magnetic field detector (3). The superconducting cylinder (1) is a hollow cylinder of which the bottom is sealed and the top is opened, is located above the rotary shaft (4), and is concentric with the rotary shaft (4); the bottom of the superconducting cylinder (1) is connected with the top of the rotary shaft (4), and the bottomof the rotary shaft (4) is connected with the rotation speed control system (5); the top cover (2) is located above the superconducting cylinder (1), and the superconducting cylinder (1) and the topcover (2) follow the rotary shaft (4) to synchronously rotate. The magnetic field detector (3) feeds the detected remaining magnetic field intensity inside the superconducting cylinder (1) back to therotation speed control system (5), the rotation speed control system (5) adjusts the rotation speed of the rotary shaft (4) and the superconducting cylinder (1), and a London magnetic field can be generated in the internal space of a superconductor by rotating the superconductor, and serve as a compensating magnetic field.
