How does a taut-band meter work?

Answer 1

To overcome the position-sensitive nature of jewel-movement meters, the taut-band movement was developed. In this type of movement, the coil is suspended in a frame by taut thin metal ribbons. A tension spring is used to maintain even pressure on these ribbons. As a amgnetic field is created in the coil, the metal bands twist and flex, allowing the coil and needle to move. When the magnetic field is removed, the opposition from the bands will move the needle back to the original position.
