A ballistic galvanometer a device to measure charge of resistance 2002 gives a full scale deflection for a charge of 640 C A coil of 300 turns and of 1000 resistance having an area of cross section A is to be constructed to measure magnetic field up to 1 6T by noting deflections in the galvanometer when the coil is suddenly removed from the field If the deflection produced should not exceed the full scale deflection the maximum area allowable for the coil is 200 mm 300 mm 400 mm 100 mm
