Question

The radial magnetic field is used in a suspended coil galvanometer to provide

• A. a uniform torque on the coil
• B. maximum torque on the coil in all positions
• C. a uniform and maximum torque in all positions
  of the coil
• D. a non uniform torque on the coil

Answer 1

The correct option is A a uniform torque on the coil

Radial magnetic field is used in a suspended coil galvanometer to provide a uniform torque on the coil because it provide uniform magnetic field.
It ensure that the magnetic field is radial and uniform through out the area of the coil
