Radial magnetic field is used in a galvanometer so that the galvanometer scale is:
Correct answer: C. Linear
- A. Exponential
- B. Circular
- C. Linear
- D. None
Explanation
While the output scale of a galvanometer can be linear, especially for applications where a direct reading of current magnitude is required, the use of a radial magnetic field does not directly determine whether the scale is linear or not. The linearity of the scale depends more on the mechanical and electrical design of the galvanometer, rather than the configuration of the magnetic field.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
