NEET Physics Magnetic Force on Current Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Magnetic moment equation | (i) NIA |
| (b) Torque on a current loop | (ii) IAB sin θ |
| (c) Direction of magnetic moment | (iii) Right-hand thumb rule |
| (d) Maximum torque condition | (iv) θ = π/2 |
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 magnetic moment is given by the equation m = NIA (Column-I a to Column-II i), the torque on a current loop is expressed as τ = IAB sin θ (Column-I b to Column-II ii), the direction of the magnetic moment is determined by the right-hand thumb rule (Column-I c to Column-II iii), and the maximum torque condition corresponds to θ = π/2 (Column-I d to Column-II iv).
