    "abstract": "Classical plasmas in thermodynamic equilibrium should be neither para- nor\ndiamagnetic due to the action of the Lorentz force. Magnetic confinement,\nhowever, is based on the observed diamagnetism of laboratory plasmas. The\napparent paradox is investigated on the basis of the resistive\nmagneto-hydrodynamic equations. It is found that, at least in simple plasma\nconfigurations, these equations do not permit a solution, i. e. the paradox\ncannot be resolved. It seems that the Lorentz force is a test-particle\napproximation which is not suitable to describe the interaction of moving\nparticles in agreement with the conservation of energy.",
