Comparative study of different current carrying structures used as electromagnetic actuator

This paper presents the comparative study of different current carrying structures used to produce electromagnetic field in magnetic based micro-pumps. The operation of the micropump lies on magnetic field that concentrates microbeads in the fluid channel and moves this cluster of microbeads in each direction forcing the fluid to flow in that direction. In this paper Finite Element simulation results of novel and simple structures which produces suitable magnetic field inside the channel is presented.
