A magnetic field is applied to a freely floating uniform iron sphere with radius R = 2.00 mm. The sphere initially had no net magnetic moment, but the field aligns 12% of the magnetic moments of the atoms (that is, 12% of the magnetic moments of the loosely bound electrons in the sphere, with one such electron per atom). The magnetic moment of those aligned electrons is the sphere’s intrinsic magnetic moment .What is the sphere’s resulting angular speed v?

Question
A magnetic field is applied to a freely floating uniform
iron sphere with radius R = 2.00 mm. The sphere initially had no
net magnetic moment, but the field aligns 12% of the magnetic moments
of the atoms (that is, 12% of the magnetic moments of the
loosely bound electrons in the sphere, with one such electron per
atom). The magnetic moment of those aligned electrons is the
sphere’s intrinsic magnetic moment .What is the sphere’s resulting
angular speed v?
