A bar magnet is cut along a transverse axis. Its dipole moment then becomes
Atwice the original value
Bhalf the original value
Cunchanged
Dzero
Answer & Solution
Correct answer: B. half the original value
The notes explicitly say that when a bar magnet is cut along a transverse axis, the pole strength remains the same but the dipole moment reduces to half.
