The National MagLab exists to provide magnetic fields that are more than a million times stronger than the Earth’s magnetic field to thousands of visiting researchers every year. Why would anyone want to do such a thing? It turns out that magnetic fields are a remarkably flexible research tool at the frontiers of research in physics, engineering, chemistry, environmental sciences, biology, and biomedicine. This talk will survey a variety of creative uses of high magnetic fields at the National MagLab to convey the excitement of present-day research using the most powerful magnets in the world.
