Chapter 32, Problem 49P
SSMThe exchange coupling mentioned in Module 32-8 as being responsible for ferromagnetism is not the mutual magnetic interaction between two elementary magnetic dipoles. To show this, calculate (a) the magnitude of the magnetic field a distance of 10 nm away, along the dipole axis, from an atom with magnetic dipole moment 1.5 × 10–23 J/T (cobalt), and (b) the minimum energy required to turn a second identical dipole end for end in this field. (e) By comparing the latter with the mean translational kinetic energy of 0.040 eV, what can you conclude?
