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) Null point location (i) 14 cm from the center of the magnet (b) Earth's magnetic field (ii) 0.36 G (c) Torque on bar magnet (iii) m × B (d) Potential energy (iv) –m . B
Choose the correct matching:
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iv, b-iii, c-i, d-ii
D
a-iii, b-iv, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
The null points of the bar magnet are correctly identified as being located at 14 cm from its center, with the Earth's magnetic field at that point being 0.36 G. The torque on the magnet is given by the expression m × B, and the potential energy is expressed as –m . B, as per the definitions in the NCERT context.
