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 a straight wire | (i) Zero contribution at center of arc |
| (b) Contribution from semicircular arc | (ii) Resembles contribution of circular loop |
| (c) Direction of magnetic field | (iii) Right-hand rule application |
| (d) Force on wire carrying current | (iv) Depends on angle with magnetic field |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
The straight wire does not contribute to the magnetic field at the center of the arc, while the semicircular arc resembles the magnetic field contribution of a circular loop. The direction of the magnetic field can be determined using the right-hand rule, and the force on the wire depends on the angle with the magnetic field as outlined in the context.
