Galvanometer is the historical name given to a moving coil
electric current detector. When a current is passed through
a coil in a magnetic field, the coil experiences a torque
proportional to the current. If the coil's movement is
opposed by a coil spring, then the amount of deflection of a
needle attached to the coil may be proportional to the
current passing through the coil. Such "meter movements"
were at the heart of the moving coil meters such as
voltmeters and ammeters until they were largely replaced
with solid state meters.

The accuracy of moving coil meters is dependent upon having
a uniform and constant magnetic field

primary of transformer connected to Dc supply in series with switch, and secondary connected on ammeter, what happens when swith On and OFF. (or) if continuously On and OFF
