Dubey and Gumbs have reported molecular-dynamics simulations for a two-dimensional, classical one-component plasma in the presence of a transverse magnetic field B. Here we combine their melting (m) curve for temperature Tm vs. B with thermodynamics to gain insight into the changes in magnetization M and entropy S across the melting line as functions of applied field B. The magnetization of the Coulomb liquid plays a central role, and yet is entirely due to particle repulsions.
