Teachers and students of statistical mechanics have to teach and study Landau diamagnetism with a cloud of doubts, since there are a large number of gaps in understanding it. Everyone know it is a quantum problem, but what many teach is the classical statistical mechanics results. We here define the limits of classical and quantum conditions with reference to Landau diamagnetism and explain when it is a quantum statistics problem and when it is a quantum mechanics problem
