WebNov 26, 2024 · The movement of a coil in a magnetic field produces a current in the coil which interacts with the magnetic field to produce a torque. This torque opposes the movement of the coil and slows the response. The magnitude of the current and hence the damping torque is dependent upon the resistance of the circuit to which the instrument is … WebFeb 24, 2012 · What is a Permanent Magnet Moving Coil (PMMC)?
