Answer 2

HERE IS YOUR ANSWER

A GALVANOMETER is a device to measure current

Galvanometer is a current sensitive device which can measure only very low currents. less than 1 ampere..

cycle consists of a coil free to rotate about a fixed axis in a uniform radial magnetic field there is a cylindrical soft iron core which not only make the field radial but also make it increase strength of magnetic field in a current flows through the coil torque acts on it ..

this torque. moves the pointer of the Galvanometer moves and shows the reading of current flowing.
