Which option correctly matches the effect of a transverse cut on a bar magnet?
APole strength halves, dipole moment unchanged
BPole strength unchanged, dipole moment halves
CPole strength doubles, dipole moment halves
DPole strength unchanged, dipole moment doubles
Answer & Solution
Correct answer: B. Pole strength unchanged, dipole moment halves
From the notes: after a transverse cut, pole strength is unaffected, but dipole moment reduces to half. So the correct pairing is unchanged pole strength and halved dipole moment.
