Why is the coil wrapped on a conducting frame in a galvanometer?

Text Solution

Verified by Experts

When a coil is rotated in the magnetic field, a variable magnetic flux is linked with the conducting frame of the coil, resulting the eddy currens in it, which opposes the cause producing it. These eddy currents in conducting frame help in stopping the coil soon i.e., in making the galvanometer dead beat.
