We present a novel system for localized magnetic manipulation of magnetotactic bacteria in microfluidic systems. Where other methods require small conductive tracks directly below the sample, the new system consists of an array of permanent magnets switchable by a drive current to either trap or guide bacteria. This allows for much higher magnetic fields at reduced power consumption. Both a theoretical analysis and experimental analysis are presented. The system is scalable and is suited for integration in microfluidics.
