The magnetic field in a Stern-Gerlach experiment varies along the vertical direction as dBz/dz = 20 T/cm. The horizontal length of the magnet is 7.1 cm and the speed of the silver atoms averages 925 m/s. The mass of the silver atoms is 1.8 x 10^-25 kg. Show that the z component of its magnetic moment is 1 Bohr magneton. What is the separation of the two silver atom beams as they leave the magnet?
