Teaching language

Suitable for English-speaking students

Objectives

Deepen knowledge of the fundamental phenomena and principles of electromagnetism. Apply differential and integral calculus techniques to formulate problems. Integrate knowledge obtained in other courses for a comprehensive approach of the physical phenomena. Describe physical situations involving the issues addressed in the course, to solve problems, and to establish links to experimental and technological situations. Present and describe relevant applications of Electromagnetism in science and technology. Prepare the students to advanced courses.

Learning outcomes and competences

The students should demonstrate good understanding of fundamental concepts of Electrodynamics.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Good basic knowledge of Electromagnetism and Mechanics, taught in the first year of the course.
Knowledge about vector calculus.

Eligibility for exams

Factors To attain frequency at Electromagnetism II:  

Presense in Problem solving lectures (TP):
- There will  be a presence record. Students exceding the limit of absences  (1/4 of given TP lectures) will be excluded from "frequencia".
- Delivering class's problems.The non delivery of 2/3 of the problems implies loosing "frequência".

Those students that have obtained "frequência" in the scholar year of  2018/19 may request TP classes dismissal. The request should be made until the end of the week preceeding the 1st lecture, by e-mail to the Responsible Lecturer.

Nevertheless,  students must attend the two envisaged tests.

Calculation formula of final grade

Evaluation considers:
two tests [75%]
TP's Problems [25%]. 

Test component: 
- intercalar test. 
- second test to be held at Normal Exam date.

For approval purposes, a global mark for each test greater than 7 over 20.

Both tests will have the same contribution for the assessemtn of this component.

In case failure, the student has the possibility of attending the exam at the "Exame de Recurso" date. This exam contributes to the 75% of the course final mark.

The Test component mark can be improved by attending the final proof at Exame de Recurso.


TP's Problems:  Each student will have deliver three individual written work produced at the TP classes, 3 times at random dates during the term. For the final mark, the two best answers will be consider, with the same weight for the mar of this component.


Final grade formula:

nota final = 0.75 x (mark teste component)  + 0.25 x (mark TP's Problems)

To pass, the final mark must have equal or greater than 10 over 20.

Classification improvement

The Test component mark can be improved by final exam in "Epoca de Recurso"
