The molar entropy of electron spins in a magnetic field B is where E = 2 B

The molar entropy of electron spins in a magnetic field B is

where ΔE = 2μ_BB is the separation in energy of the two spin states in a magnetic field, and μ_B is the Bohr magneton, μ_B = 9.274 * 10^–24 J · T^–1. Plot this function against temperature for the following values of B: 0.1 T, 1 T, 10 T, and 100 T.
