Summary of Intended Learning Outcomes
|- Understand the foundational principles of dynamics, electromagnetism, and relativity and how they relate to broader physical principles.
- Understand in detail the structure of Maxwell electromagnetism and Special relativity, and the relation between them.
- Be able to formulate and develop the inter- relation of charges, currents, fields, potentials and forces using vector, tensor and integral calculus in index notation, both in 3 and 3+1 dimensions.
- Be able to formulate and solve a range of static boundary value problems, and problems with time dependent charges, currents, and electromagnetic fields.
- Derive and understand the relation of electromagnetism to wave propagation, optics, and the generation of classical radiation.
- Devise and implement a systematic strategy for solving a complex problem by breaking it down into its constituent parts.
- Use the experience, intuition and mathematical tools learned from solving physics problems to solve a wider range of unseen problems.
- Resolve conceptual and technical difficulties by locating and integrating relevant information from a diverse range of sources.
