Experiments on dust confinement in a magnetized plasma region in front of a small positively biased electrode are analyzed. The axial confinement of d = 1{mu}m particles can be quantitatively described by a balance of ion drag and electric field force. Radial confinement is due to strong electric fields. It is demonstrated that this anodic plasma has a distinctly different discharge mechanism from fireballs with ionizing double layers. The plasma is stable against potential relaxations but shows a strong ion cyclotron mode in the shear layer at the anode edge.
