The invention discloses an electromagnetic torque spanner. The electromagnetic torque spanner comprises a handle rod and an outer circular shell integrated with the handle rod. An iron core, a compression chamber and an air storage chamber are arranged in the handle rod, and the iron core is sleeved with a coil. An air inlet through hole structure enabling the outside to communicate with the compression chamber and an air inlet through hole structure enabling the compression chamber communicate with the air storage chamber are formed in the handle rod. A 51 single-chip microcomputer is installed on the side face of the handle rod. A permanent magnet is arranged in the compression chamber and located at one end of the iron core. A valve element plate is fixed to one end face of the permanent magnet. Through hole structures are formed in the center of the valve element plate and the center of the permanent magnet. According to the electromagnetic torque spanner, screwed bolts can be effectively controlled to the maximum extent; moreover, the electromagnetic torque spanner adopts electromagnetic control, thereby being controllable; and in addition, the screwed bolts can be controlledto be effectively adjusted to the maximum extent according to the magnitude of currents, and thus the adjustment range is wide.
