Concept explainers
The magnitude of the dipole moment associated with an atom of iron in an iron bar is 2.1 × 10–23 J/T. Assume that all (he atoms in the liar, which is 5.0 cm long and has a cross-sectional area of 1.0 cm2, have their dipole moments aligned, (a) What is (he dipole moment of the bar? (b) What torque must he exerted to hold this magnet perpendicular to an external field of magnitude 1.5 T? (The density of iron is 7.9 g/cm3.)
