In a moving coil galvanometer, what is meant by a radial magnetic field ?

A rectangular coil of 50 turns, each of area 0.1 m^(2) and carrying a current of 1 A is held perpendicular to a magnetic field of 0.1 T. What is the torque acting on the coil?

In a moving coil galvanometer, there is a coil of copper having number of insulated turns N, each of area A. The coil is suspended in a radial magnetic field B. The moment of inertia of the coil about its rotational axis is I. The scale divisions in the galvanometer are n and resistance of the coil is R. If a current i_0 in the coil produces a deflection of pi//3 radian to the pointer of galvanometer, the value of torsional constant of the spring is
