Magnetic fields move microbeads Image TRN 032801

Description: The top two images show paths etched in an electromechanical chip. The gold squares on the top image are wires. The bottom image shows a magnetic bead on one of the paths. The beads can be moved by adjusting the current running through the wires, which changes the electromagnetic fields around the wires.
