AIPMT PRELIMS 2005 Physics Magnetic Properties of Materials MCQ Question
If the magnetic dipole moment of an atom of diamagnetic material, paramagnetic material and ferromagnetic material are denoted by μd, μp and μf respectively, then :
μd ≠ 0 and μf ≠ 0
μp = 0 and μf ≠ 0
μd = 0 and μp ≠ 0
μf ≠ 0 and μp = 0
Correct Answer
Detailed Explanation
Diamagnetic materials have no net magnetic moment (μd = 0), paramagnetic materials have a small net magnetic moment (μp ≠ 0), and ferromagnetic materials have a large net magnetic moment (μf ≠ 0).
