The magnetic field is along the z axis in a Stern-Gerlach experiment. The force it exerts on a magnetic dipole with dipole moment is proportional to: B) B² C) dB/dz D) d²B/dz² E)$\int$B dz

Question

Quizplus · Accepted Answer

The force exerted by a magnetic field on a magnetic dipole is given by the formula F = dB/dz, where dB/dz is the gradient of the magnetic field along the z axis. Therefore, the force it exerts on the given magnetic dipole is proportional to dB/dz.
