Physics-Bar Magnet
NEET Physics Bar Magnet Match the Following Question
Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Magnetic poles | (i) Cannot be isolated |
| (b) Dipole moment | (ii) m × B |
| (c) Magnetic field | (iii) Zero force in uniform field |
| (d) Potential energy | (iv) –m . B |
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
Magnetic poles cannot be isolated as stated in the summary, the dipole moment experiences torque m × B in a uniform magnetic field, and the potential energy is given by the expression –m . B. The force on a magnet in a uniform magnetic field is indeed zero.
