What is the principle of a moving coil galvanometer ?

Text Solution

Verified by Experts

Moving coil galvanometer is based on the fact that when a current carrying coil is placed in a uniform magnetic field, it experiences a torque.
`therefore` current in the coil (i) `prop` deflecting angle `(theta)`.
