We have studied the effects of the magnetic field on the active electronegative plasma
sheath properties and dust charging process in the sheath region for two different collisional
models: constant ion mean free path and constant ion mobility using 1d3v fluid
hydrodynamics model. It is found that the magnetic field strength and choice of collisional
models have a significant effect on the active plasma sheath characteristics and charging of
an isolated dust grain. The sheath criterion for an active electronegative magnetized plasma …
