state gov BSSC Laboratory Assistant Mock Test Series 2025 Physics Moving Charges and Magnetism The Moving Coil Galvanometer
Certain galvanometers have a fixed core made of non magnetic metallic material. The function of this metallic material is
1
To produce large deflecting torque on the coil
2
To bring the coil to rest quickly
3
To oscillate the coil in magnetic field for longer period of time
4
To make the magnetic field radial
