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
Choose the correct matching:
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).
