The invention discloses a novel electromagnetic torque wrench. The novel electromagnetic torque wrench comprises a handle lever and an outer ring shell, wherein the handle lever and the outer ring shell are of an integrated structure; an iron core sleeved with a coil, a compression chamber and an air storage chamber are arranged in the handle lever; an air inlet through hole structure enabling theoutside to communicate with the compression chamber and an air inlet through hole structure enabling the compression chamber to communicate with the air storage chamber are arranged in the handle lever; a 51 single chip microcomputer is installed on the side face of the handle lever; a permanent magnet is arranged at the position, located at one end of the iron core, of the interior of the compression chamber; a valve element plate is fixedly arranged on one end face of the permanent magnet; and the center of the valve element plate and the center of the permanent magnet are of a through holestructure. The novel electromagnetic torque wrench can carry out effective maximum force control over screwed bolts. Besides, the novel electromagnetic torque wrench uses electromagnetism for controland has controllability. The novel electromagnetic torque wrench can control effective maximum force adjustment of the screwed bolts according to the magnitude of currents, and the adjustment range is wide.
