    "abstract": "It is argued that continuum realisations of distributions of collisionless\ncharged particles should accommodate a dynamically evolving number of electric\ncurrents even if the continuum is composed of only one species of particle,\nsuch as electrons. A model is proposed that self-consistently describes the\ninteraction of such a continuum and its electromagnetic field. It is formulated\nusing a Lagrangian approach and employs a \"folded\" flow map to describe the\nbulk particle motion. An asymptotic perturbation scheme is developed to analyse\nultra-relativistic multi-component current configurations. The model is fully\nrelativistic and is formulated over Minkowski spacetime using intrinsic tensor\nfield theory.",
