How does a moving iron analog meter work?
Moving Iron Vane Movement The moving iron vane movement can be used to measure both AC current and voltage. By changing the meter scale calibration, the movement can be used to measure DC current and voltage. The moving iron vane meter operates on the principle of magnetic repulsion between like poles. The measured current flows through a field coil which produces a magnetic field proportional to the magnitude of current. Suspended in this field are two iron vanes attached to a pointer. The two iron vanes consist of one fixed and one moveable vane. The magnetic field produced by the current flow magnetizes the two iron vanes with the same polarity regardless of the direction of current through the coil. Since like poles repel one another, the moving iron vane pulls away from the fixed vane and moves the meter pointer. This motion exerts a force against a spring. The distance the moving iron vane will travel against the spring depends on the strength of the magnetic field. The strength of the magnetic field depends on the magnitude of current flow. Figure 3 Moving Iron Vane Meter Movement As stated previously, this type of meter movement may also be used to measure voltage. When this type of movement is used to measure voltage, the field coil consists of many turns of fine wire used to generate a strong magnetic field with only a small current flow.
Why moving iron is used in both AC and DC current?
A moving iron instrument works by means of a coil that attracts a moving iron mass that is attached to a pivoted pointer which moves across a graduated scale. The iron mass will be attracted towards the coil, regardless of the magnetic polarity of the coil. So, as an AC current continually reverses the magnetic polarity of the coil, the iron mass is always attracted towards the coil, never repelled by it. Similarly, a moving iron instrument doesn't care in which direction a DC current is flowing. So the instrument works equally well with both AC and DC currents. Moving iron instruments, however, are not as accurate as moving coil instruments which, of course, are sensitive to the direction of current.

Is digital ammeter is a moving iron Instrument or moving coil instrument?
Neither. Both moving iron and moving coil instruments are analogue instruments, relying on mechanical movement to display a measurement. A moving iron instrument works on the principle of attraction or replusion between an electromagnet and an iron armature to drive its pointer. A moving coil instrument works on the principle of the interaction of two magnetic fields to drive its pointer.A digital instrument, on the other hand, is completely solid-state, using electronic circuits to digitally process the information supplied by the circuit under test, and then displays the result using a digital output.
Is Voltmeter is a moving iron Instrument or moving coil instrument?
AC Voltmeter is a moving iron instrument.AnswerA voltmeter can be a moving-coil instrument, or a moving-iron instrument. Moving-coil instruments are much more accurate than moving-iron instruments and cost a great deal more.
