Attachment characteristics of charged magnetic cubic particles to two parallel electrodes (3D Monte Carlo simulations)

摘要

The cubic particles magnetised along a diagonal direction are negatively charged and confined between two parallel electrode walls. These particles have a tendency to migrate toward and attach to the positive electrode together with the formation of chain-like clusters. We here have focused on three cases of external magnetic field direction. In the case of an external magnetic field applied in the oblique direction to the electrode wall, almost all the constituent particles of the chain-like clusters attach to the positive electrode wall in a face-to-face contact manner. In the case of an external magnetic field applied along the surface of the electrode wall, the chain-like clusters are formed in the space of the two parallel walls. In the case of an external magnetic field applied normal to the electrode wall, the tendency for the particles to form chain-like clusters along the electrode wall is the weaker among the three field directions. In this situation, the cubic particles attach to the wall surface with a vertex of the cube contacting with the surface, and from the anchored particle, a chain-like cluster is formed in the space between the two parallel walls.
