Course Highlights
This course includes homework assignments and extensive lecture notes.
Course Description
This course focuses on one important engineering application of superconductors  the generation of largescale and intense magnetic fields. It includes a review of electromagnetic theory; detailed treatment of magnet design and operational issues, including "usable" superconductors, field and stress analyses, magnet instabilities, ac losses and mechanical disturbances, quench and protection, experimental techniques, and cryogenics. The course also examines new hightemperature superconductors for magnets, as well as design and operational issues at high temperatures.
