title: Motion of charged particles near magnetic-field discontinuities.
abstract: Charged particles near discontinuities in magnetic fields, so-called "boundary particles," can be constrained to remain near the discontinuity, even an arbitrarily fractured discontinuity, as the particle drifts along the fractured boundary. These particles are shown to exhibit new and interesting effects along broken and branching surfaces, including the wetting of fractured surfaces.
