Objectives

The objectives of this course unit are such that students may acquire basic knowledges of Electromagnetism
(an underlying science of Electrical Engineering) and that students may develop their own personal and professional skills and attributes.

At the end of this course unit students are exepcted to have acquired the following skills.

1. Technical Knowledge and Reasoning (CDIO 1.1,1.2)
- To apply correctly the laws which rule the electromagnetic phenomena.
- To present Electromagnetism as an unified model of the different electromagnetic phenomena observed in Nature and used in Technology.
- To use the proper technical terminology in order to explain the different electromagnetic concepts and phenomena.
- To describe and explain some of the basic applications of Electromagnetism, such as, capacitors, resistors, coils, electric motors, electric generators, electric transformers, semiconductors, diodes, magnetic circuits.

2. Personal and Professional Skills and Attributes (CDIO 2.1,2.3,2.4,2.5)
- To enumerate Pólya's Four Steps and through these to acquire skills in order to solve critically and autonomously exercises about the course subjects.
- To develop a critical attitude towards the final result, namely, using dimensional analysis, estimative of the expected order of magnitude, interplay between the different quantities and solution's behaviour in specific limit cases.
- To acquire the discipline to work continuously during the semestre.
- To attain skills concerning written communication.
- To develop an attitude respecting ethical values such as mutual respect, responsibility and honesty.

3. Interpersonal Skills (CDIO 3.1,3.2)
- To acquire skills concerning teamwork.
- To attain skills concerning oral communication.

Eligibility for exams

To attain admission to final exams students must:
- not exceed 3 absences to exercise classes.
- get a minimum grade of 7 (out of 20) in the distributed evaluation.

Distributed evaluation is performed by 1 midterm exam. The midterm exam will consist of one exercise (10 points) and ten multiple choice questions (4 points). Midterm exam will last 1h:30 minutes and will be performed at a date to be announced.

Students that attained the conditions of admission to final exams in the previous academic year are dismissed from attending classes, being the previous distributed evaluation grade kept. Nonetheless, these students can choose to enroll on one exercise class and to be submitted to the distributed evaluation, being the previous distributed evaluation grade canceled. This option is irreversible.

Please see also Article 4th of "Normas Gerais de Avaliação da FEUP".

Calculation formula of final grade

AD - Distributed Evaluation (0 to 20 points)
EF - Final Exam (0 to 20 points)
CF - Final Mark (0 to 20 points)

If AD >= 7 then the student is admitted to final exams.

In order to pass the course (final mark CF >= 10 points) students must get a minimum of 8 points on the final exam.
Distributed Evaluation has a 40% weight and Final Exam a 60% weight.

If EF >= 8 then CF = MAX (EF ; 0.4 * AD + 0.6 * EF)
else CF= EF

Examinations or Special Assignments

n.a

Special assessment (TE, DA, ...)

- Students that have a special status (working students,military students) during the present academic year are dismissed from attending the classes and therefore to get a distributed evaluation grade. For these students the final mark will be that of the final exam. Nonetheless, these students can choose to enroll on one class and submit to the distributed evaluation. This option is irreversible.

- Please see also Articles 4th and 6th of "Normas Gerais de Avaliação da FEUP".

Classification improvement

Through the 2nd round Final Exam.

Final Mark will be evaluate as follows:

CF = max (0.4 * AD + 0.6 * EFN, 0.4 * AD + 0.6 * EFR, EFR)

where CF is the Final Mark (from 0 to 20 points), EFN is the 1st. round Final Exam ("Exame de Época Normal) grade (from 0 to 20 points), AD is the Distributed Evaluation grade (from 0 to 20 points) and EFR is the 2nd. round Final Exam ("Exame de Época de Recurso") grade (from 0 to 20 points).

Observations

- Weekly time of study, beyond classes, is expected to be around 6 hours.

- Informations and support material are available at moodle web page of the course: http://moodle.fe.up.pt/0809/course/view.php?id=169

- At the end of the course unit students are exepcted to have acquired the demanding skills to use without any difficulty the textbook "A Student's Guide to Maxwell's Equations" of Daniel Fleisch (see bibliography).

- Any attempt of FRAUD during the distributed evaluation corresponds to fail immediately the course.
