how do you find out whether a given meter is a moving coil or moving iron?

I'll drink to that mr Del although haven't seen many moving iron meters for many years suppose because moving coils have much lower inertia.

Hi,

Congratulations for landmark 10000/200 (10000 test runs and 200 centuries on CR4=Cricket4)

Scale of moving coil meters are linear, where as moving iron are non linear scale meters.also moving coil offers better needle damping than of moving iron.

Not correcting you but linearity of an meter is mostly a design related issue. You can make as easily linear or non-linear applications both ways

one can improve linearity of a moving iron meter too, but can not call it a practically linear meter, on other hand a moving coil meter exhibit enough linearity for all practical purposes, however a badly designed moving coil meter can have gross non-linearity.

Moving iron meters can not be made fully linear because of eccentric nature of the iron leaf provided, and It is not going to offer any deflection if you try to put it in the center of coil, so no choice left,but keep it eccentric and live with nonlinearity.

It is given as a symbol on the meter dial. An MI meter has a symbol such as an inverted U with a horizontal I underneath it. An MC meter has a sort of a SIGMA symbol. (I am sorry I am unable to draw symbols here).
