Question

To make the magnetic field radial in a moving coil galvanometer

Answer 1

Answer:

The uniform radial magnetic field keeps the plane of the coil always parallel to the direction of the magnetic field. ... The radial magnetic field provided to the moving coil of a galvanometer results in maximum torque on the coil in presence of current. Since, the field is always perpendicular to the area of the coil.
