(i) The galvanometer can be made extremely sensitive.
(ii) Since the magnetic field B is very high, therefore, the external magnetic fields cannot appreciably after the deflection of the coil. So, the galvanometer can be used in any position.
(iii) Since the deflection of the coil is proportional to current, therefore, linear scale can be used.
(iv) Since the coil is wound over metallic frame, therefore, damping is produced by eddy currents. So, the galvanometer coil comes to rest quickly. This type of galvanometer is called a periodic or dead beat galvanometer.
The galvanometer can be made ballistic by winding the coil on a non-conducting frame of ivory or ebonite.
(v) The lamp and scale arrangement used to measure the deflection of the coil makes the galvanometer very sensitive.
