Triplet excited states some organic molecules have a triplet (S = 1) excited state at an energy
Question:
Triplet excited states some organic molecules have a triplet (S = 1) excited state at an energy kBΔ above a singlet (S = 0) ground state.
(a) Find an expression for the magnetic moment (μ) in a field B.
(b) Show that the susceptibility for T >> Δ is approximately independent of A.
(c) With the help of a diagram of energy levels versus field and a rough sketch of entropy versus field, explain how this system might be cooled by isentropic magnetization (not demagnetization).

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. The video shows the practical implications of magnetic force around different objects.
