Can you believe it? We are already at week three. This week is all about magnets and how magnets change when they are made small. Magnetism is quite mysterious and the foundation of such cool technologies as flash drives and MRI imaging. Nanotechnology has played a crucial role in advancing all of these diverse applications and this week you'll gain some insight into how that is possible.
