In a moving coil galvanometer, the deflection of the coil θ is related to electric current I by the relation
Correct answer: A. I is proportional to tan(θ)
- A. I is proportional to tan(θ)
- B. I is proportional to θ
- C. I is proportional to θ^2
- D. I is proportional to θ^1/2
Explanation
A is the correct answer. In a moving coil galvanometer, the deflection of the coil (θ) is related to the electric current (I) by the tangent law: I∝tan(θ).

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.
