NEET Physics Magnetic Force on Current Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Magnetic field due to straight segments | (i) Contributes to magnetic field |
| (b) Force on wire in magnetic field | (ii) Depends on current and angle |
| (c) Semi-circular arc contribution | (iii) No contribution to magnetic field |
| (d) Magnetic force on perpendicular wire | (iv) Balanced by gravitational force |
a-iii, b-ii, c-i, d-iv
a-i, b-ii, c-iii, d-iv
a-ii, b-iv, c-i, d-iii
a-ii, b-i, c-iv, d-iii
Correct Answer
Detailed Explanation
The straight segments of a wire carrying current do not contribute to the magnetic field at the center of the arc (a-iii). The force on a wire in a magnetic field depends on both the current and the angle it makes with the field (b-ii). The semi-circular arc contributes to the magnetic field, while the magnetic force on a perpendicular wire is balanced by gravitational force (d-iv).
