Answer:
Explanation:The pole pieces of the galvanometer are made concave so that the current-carrying coil and the magnetic field are always perpendicular to each other. Concave magnetic pole always produces a radial magnetic field. The radial field will always be perpendicular to the conductor rotating about the axis.
