The potential energy of a magnetic moment in an external magnetic field is U = -...

The potential energy of a magnetic moment in an external magnetic field is U = - ??B. U is smallest when B is parallel to ? and largest when it is antiparallel. Since the magnetic moment of the electron is directed opposite to its spin (because it has a negative charge), the electron’s energy is highest when the spin is parallel to B. The two possible energy states for the electron are the spin up state (ms = 1212) and...

The energy E of a magnetic moment ~µ in a magnetic field B~ is E = −~µ · B~ . Consider an isolated particle with magnetic moment ~µ. The projection of ~µ along z can only take two values: (~µ)z = ±µB, where µB is a constant called the Bohr magneton. i) What are the particle energies E± corresponding to the two projections when the particle is subject to a magnetic field B~ ≡ (0, 0, Bz) along the z-axis...
