Using basic theoretical considerations we show that the elastic continuum and conduction electrons interact via a vector field, to first order. This interaction must therefore be closely related to a magnetic interaction. We then study the magnetic interaction between conduction electrons using the Darwin approach and the free electron gas model. We show that pairing of conduction electrons may result and we calculate the total energy lowering due to the Darwin term in the Hamiltonian. The relevance of the results to superconductivity is considered.
