A one-dimensional collisionless kinetic model is developed for electron collection to a positively biased object in magnetized plasmas. The cross-field flow into the collection tube is modelled by accounting consistently for particle exchange between the collection flux tube and the outer plasma. Numerical solutions of the self-consistent plasma/sheath equations are obtained for a stationary plasma. The spatial dependence of the electron distribution function, its moments (density, particle flux, and temperature), and potential at sheath are obtained.
