Role within programme and connections to other courses. This course pursues high level extension and application of electromagnetic theory. It connects to and extends relativistic mechanics (started in Mechanics I), and illuminates ideas from atomic/molecular physics, plasma physics and other fields. Content. Magnetohydrodynamics, relativistic four-vectors and four-tensors, force and Minkowski force, covariant formulation of E/M fields, an E/M perspective on quantum field theory.
