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 the current. On excitement, the coil behaves as an electromagnet, and the vane moves in such a way that the flux increases. Force is produced in the direction which results in the increment of coil inductance.

How to Calculate Deflecting Torque of Moving Iron?

Deflecting Torque of Moving Iron calculator uses Torque=0.5*((Current in Coil)^2)*Change in Inductance to calculate the Torque, The Deflecting Torque of Moving Iron is produced due to a change in inductance of inductive coils and is proportional to increment in inductance with deflection increment. Torque and is denoted by Td symbol.

How to calculate Deflecting Torque of Moving Iron using this online calculator? To use this online calculator for Deflecting Torque of Moving Iron, enter Current in Coil (i) and Change in Inductance (dL/dθ) and hit the calculate button. Here is how the Deflecting Torque of Moving Iron calculation can be explained with given input values -> 2.000E-5 = 0.5*((0.002)^2)*10.

FAQ
