It is advisable to have passed the subject Electricity and Magnetism of the first course of Physics.

Have a basic knowledge of the electromagnetic field, from electrostatics and magnetostatics (in vacuum and in material media) to electromagnetic induction and Maxwell's equations.

To be able to calculate various solutions of Maxwell's equations, including electromagnetic waves and their propagation.

- Develop strategies for analysis, synthesis and communication that allow the concepts of physics to be transmitted in educational and dissemination-based contexts
- Formulate and address physical problems identifying the most relevant principles and using approximations, if necessary, to reach a solution that must be presented, specifying assumptions and approximations
- Know the fundamentals of the main areas of physics and understand them
- Make changes to methods and processes in the area of knowledge in order to provide innovative responses to society's needs and demands.
- Use critical reasoning, show analytical skills, correctly use technical language and develop logical arguments
- Use mathematics to describe the physical world, selecting appropriate tools, building appropriate models, interpreting and comparing results critically with experimentation and observation
- Work independently, have personal initiative and self-organisational skills in achieving results, in planning and in executing a project

- Correctly handle vector calculus.
- Describe electrostatic phenomena.
- Describe magnetostatic phenomena.
- Describe phenomena that involve time-dependent electromagnetic processes.
- Formulate and solve mathematical problems concerning electrostatic phenomena.
- Formulate and solve mathematical problems on electromagnetic phenomena that involve time-dependent processes.
- Identify situations in which a change or improvement is needed.
- Solve complex problems of an electromagnetic nature from the establishment of hypotheses that, even being approximate, contain the essence of physics in the original problem.
- Translate specific physical problems of electromagnetic nature to a mathematical formulation that allows subsequent resolution, either exact or approximate.
- Transmit, orally and in written format, physical concepts of a certain complexity, making them understandable to non-specialist settings.
- Use critical reasoning, show analytical skills, correctly use technical language and develop logical arguments
- Work independently, take initiative itself, be able to organize to achieve results and to plan and execute a project.

**Deliverable: **Students should deliver, in written format, the solucion of some problems that will be announced prevviously.

**Partial exams 1-2-3**: PTheory questions and solutions of problems (written format) of the part of the sylabus that have already taken at the moment of the exam. Theory questions could be explicit or embeded in some particular problem.

**Retaken exam:**

- The deliver part cannot be retaken.

- If the average of the qualification in partial 1 and 2 is less that 5 (over 10), there will be a single retaken exam of these parts jointly (50%). There is no option of retake individually these exams.

- If the average of the qualification in partial 3 is less that 5 (over 10), there will be a retaken exam of this part (40%).

- All the retaken exams will be done the same day (the official day)

** **

**Single evaluation: S**tudents allowed for the single evaluation, must make 3 exams (the day of the partial 3), corresponding to each of the partial exams. The same day, the written solution of some problems previously announced should be delivered. The retaken process is the same as of the rest of the students.

**UAB Regulations: **To be able of retaken some exam, the student should have been evaluated of, al least, 2/3 of the total of the evaluation. (In this subject, the student should have been evaluated of the 3rd and the 1st or the 2nd partials (65%)).

**UAB Regulations**: In the event that the student realizes any irregularity that might lead to a significant variation in the qualification of evaluation activity, he or she will qualify with 0 this evaluation activity, irrespective of the disciplinary process that could be started. If there are several irregularities in the evaluation of the same subject, the final qualification of this subject will be 0.

Any plagiarism (total or partial), copying or attempted copying, letting oneself be copied, etc., in any of the evaluable activities will be considered "irregularities leading to a significant variation in the qualification".

It is imperative that students make their exams in the group in which they are enrolled.
