All the Best! 1 / 10 A material with antiparallel and unequal moments is ___ . antiferromagnetic ferromagnetic ferrimagnetic paramagnetic 2 / 10 How does magnetisation M depend on external field H for a linear medium? M = μ₀H M = H² M = H/χₘ M = χₘH 3 / 10 The SI unit of pole strength is: A A/m A·m A·m² 4 / 10 Absence of monopoles implies that field lines: start and end at charges diverge outward form closed loops terminate at poles 5 / 10 Why does magnetic susceptibility of ferromagnets drop sharply at Curie point? Dipoles lose alignment due to heat Domain grows stronger Poles exchange μ₀ increases 6 / 10 Magnetic moment of a loop of radius 0.1 m carrying 2 A is ___ . 0.02 A·m² 0.04 A·m² 0.06 A·m² 0.01 A·m² 7 / 10 Relation between B, H and M is ___ . B = μ₀HM B = M/H B = μ₀H/M B = μ₀(H + M) 8 / 10 What would be the effect on compass needle near a current-carrying wire? It deflects due to magnetic field It breaks It aligns vertically No effect 9 / 10 If horizontal component H = 0.3 G and dip = 60°, then total field B = ___ G . 0.6 0.3 0.52 0.15 10 / 10 What is the magnetic dipole moment of a circular loop of radius 0.05 m carrying current 5 A? 0.04 A·m² 0.05 A·m² 0.039 A·m² 0.1 A·m² Your score is 0% Restart quiz
