Theory of classical electrodynamics (description of electromagnetic phenomena in vacuum and in materials) and theory of special relativity, including relativistic electrodynamics. The two theories (electrodynamics and relativity) are presented with an axiomatic approach that emphasizes the inductive/deductive approach of physics. The comprehension of physical phenomena will be encouraged, rather than the mere memorization of formulas and concepts.
At the end of the course, the student will be able to critically analyze physical phenomena dominated by electromagnetism and be able to give an explanation of them. The student will know the main results of electrodynamics and of the special theory of relativity.
Course Prerequisites
Fundamental concepts of Physics, such as force, energy, power, etc. Vectorial and matrix calculus (Matrix algebra). Integral calculus in multiple dimensions.
Teaching Methods
The lectures are blackboard-based (no powerpoint). Some devices based on electrodynamics will be presented (e.g. Electrical motor, hard disk, etc.) Interactions (questions, observations and feedback) are encouraged.
Assessment Methods
Oral examination. The student can choose a topic to begin the examination (also among the optional topics).
During the exam the student must prove he/she has comprehended the subject and is capable of autonomous realaboration of the concepts. The examination is structured in a way to discourage the mere memorization of the subject.
