The coil of a galvanometer is suspended between the poles of a U-shaped magnet which are:
Correct answer: A. Concave shaped
- A. Concave shaped
- B. Convex shaped
- C. Plane-shaped
- D. Spherical shaped
Explanation
Concave refers to a surface or structure that curves inward, like the inner surface of a bowl. The poles of a U-shaped magnet are typically flat or slightly rounded, rather than concave.

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.
