Torque acting on a current loop in a uniform magnetic field is equal to

A current carrying loop in a uniform magnetic field will experience

What is the function of the radial magnetic field in the moving coil galvanometer?

Assertion Net torque in the current carrying loop placed in a uniform magnetic field (pointing inwards) is zero. Reasonl Magnetic moment (M) is inwards.
