A moving coil galvanometer works on the principle that a current-carrying coil placed in a magnetic field experiences a torque. The torque causes the coil to rotate, and the rotation is proportional to the current flowing through the coil. The galvanometer consists of a rectangular coil of wire suspended between the poles of a strong magnet. The coil is free to rotate about its vertical axis. project file on moving coil galvanometer for class 12 pdf
When a current flows through the coil, it experiences a force due to the interaction with the magnetic field. The force on the coil is given by: \[F = BIL\] A moving coil galvanometer works
