NEET Physics Magnetic Force on Current Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Torque on a current loop | (i) Depends on angle θ |
| (b) Direction of magnetic moment | (ii) Right-hand thumb rule |
| (c) Magnetic field in a solenoid | (iii) Uniform inside the solenoid |
| (d) Force on a current-carrying wire | (iv) Proportional to current and length |
a-ii, b-i, c-iii, d-iv
a-iv, b-ii, c-i, d-iii
a-iii, b-iv, c-ii, d-i
a-i, b-iii, c-iv, d-ii
Correct Answer
Detailed Explanation
The torque on a current loop depends on the angle θ between the magnetic moment and the magnetic field. The direction of the magnetic moment is determined by the right-hand thumb rule. The magnetic field inside a solenoid is uniform, and the force on a current-carrying wire is proportional to both the current and the length of the wire in the magnetic field.
