What is Moving Iron Instrument?

A moving-iron instrument is generally used to measure alternating voltages and currents. The moving element is an iron vane/plate. This iron is moved in a magnetic field produced by a stationary coil, which is excited by current. On excitement, coil behaves like an electromagnet and vane moves in such a way that the flux increases. Force is produced in the direction which results in the increment of coil inductance
