Exactly what are magnets? How can a nail be turned into a magnet by applying another magnet? It turns out the answer to these questions plays a role in today's technologies—computers and the Internet—as well as tomorrow's. In this talk, Ben McMorran discusses how these questions can be answered by looking at magnets at nanometer length scales. He also discusses how various magnetic microscopes work, the role that electron angular momentum plays in magnetic material, and efforts to manipulate this angular momentum using "sculpted" electrons.
