Question

[Ans: 2.34 x 10-8 s)
14. A moving coil galvanometer has been
fitted with a rectangular coil having 50
turns and dimensions 5 cm x 3 cm. The
radial magnetic field in which the coil is
suspended is of 0.05 Wb/m². The torsional
constant of the spring is 1.5 x 10-9 Nm/
degree. Obtain the current required to be
passed through the galvanometer so as to
produce a deflection of 30°.
