Physics-Magnetic Force on Current
NEET Physics Magnetic Force on Current Match the Following Question
Type: Match the Following-match the column-Easy-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Magnetic torque NIAB | (i) Tendency to rotate the coil |
| (b) Restoring torque kφ | (ii) Balance magnetic torque |
| (c) Angular deflection φ | (iii) Indication on scale |
| (d) Torsional constant k | (iv) Restoring torque per unit twist |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iii, b-iv, c-i, d-ii
D
a-iv, b-iii, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
The magnetic torque NIAB tends to rotate the coil (a-i), and the restoring torque kφ balances it (b-ii). The angular deflection φ is indicated on the scale (c-iii), and the torsional constant k is defined as the restoring torque per unit twist (d-iv).
