Presented is a new class of numerical algorithms for computer simulation of low frequency (..omega..very-much-less-than..omega../sub pe/, ..omega../sub ce/) electromagnetic and electrostatic phenomena in magnetized plasma. Maxwell's equations are solved in the limits of negligible transverse displacement current (Darwin's model) and quasineutrality. The numerical models treat electrons as a massless fluid and ions as particles. The numerical stability of the algorithms is investigated analytically and verified by computer experiments. The numerical algorithms, in both linearized and fully nonlinear forms, are successfully applied to the study of linear microinstabilities and the efficiency of injected small amplitude currents in causing the local reduction of the external magnetic field in magnetically confined plasmas.
