what is the difference between moving coil galvanometer and pivoted galvanometer?

Open in App

Solution

Moving coil galvanometer: In this galvanometer, magnet is fixed and current carrying coil deflects.

Pivoted Galvanometer: This is also called as moving magnet type galvanometer. In this galvanometer, current carrying coil is fixed and magnet deflects. Ex: Tangent galvanometer.
