Magnetic microscope image of three nanomagnetic computer bits. Each bit is a tiny bar magnet only 90 nm long. The microscope shows a bright spot at the “North” end and a dark spot at the “South” end of the magnet. The “H” arrow shows the direction of magnetic field applied to switch the direction of the magnets.
