Why are moving iron instruments unpolarized?

Moving-coil instruments are polarised, not unpolarised. This is because they are direct current instruments, and the direction of the current determines the direction in which the instrument's point will move. If a moving coil instrument is connected incorrectly, then the instrument will try and read 'downscale' -in other words, the resulting torque will try and move the pointer backwards.AnswerA moving-iron meter operates by the repulsion between a fixed iron pole piece, and a moving iron pole piece to which the pointer is attached. The magnetic polarity of the fixed and moving pole pieces is determined by the direction of current flowing though a coil. The magnetic polarities induced into the fixed and moving iron pole pieces, when the current flows in one direction, are both north; and, when the current flows in the oppositedirection are both south. So the pole pieces always repel each other, regardless of current direction.
