MHT CET Physics question
A 200 turn rectangular coil measuring 0.02 m 0.08 m of an ammeter is in a magnetic field of induction 0.2 tesla. The torsional constant of the suspension fibre is newton metre/degree. The maximum reading of the ammeter corresponds to a deflection of the coil through 45. If the magnetic field is radial, then the maximum current that can be measured with this ammeter is
