Objectives

At the end of this course unit, the student must be able:

- to describe and explain the essential concepts about electric field, electric current, electric circuits, magnetic field, electromagnetic induction, electromagnetic waves, properties of light (propagation, reflection, refraction) and geometric optics.

- to present electromagnetism as an unified model of the different electromagnetic and optical phenomena observed in nature and used in technology.

- to identify and distinguish stationary phenomena and time-dependent phenomena.

- to describe and explain some of the basic applications of electromagnetism, such as, capacitors, resistors, coils, electric motors, electric generators, electric transformers, and basic instruments of geometric optics, such as, mirrors, lenses, microscopes.

- to explain on an elementary ground the microscopic mechanisms behind the studied macroscopic phenomena: atomic structure of matter, polar and non-polar materials, Drude model of electric conductivity, microscopic currents, interaction between radiation and matter (absorption and emission).

- to solve critically and autonomously exercises about the course subjects.

Students are expected to develop skills concerning group work, work discipline during the semester, and to develop an attitude respecting ethical values such as mutual respect, responsibility and honesty.

Eligibility for exams

To attain admission to final exams students must:
- not exceed 9 absences to lessons.
- get a minimum grade of 10 (out of 20) on the distributed evaluation.

Distributed evaluation is performed by 4 midterm exams. Each midterm exam will consist of one exercise (16 points) taken out from an exercise pool (previously announced to students) and of two multiple choice questions (4 points). Distributed evaluation grade is the average over the midterm exams. Midterm exams will last 30 minutes and will be performed at the beginning of the lesson.

Midterm exams schedule:
MT1 - 20 March
MT2 - 3 April
MT3 - 15 May
MT4 - 29 May

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 class and submit 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 >= 10 then the student is admitted to final exams.

In order to pass the course (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 than CF = 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, etc.) 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 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 grade (from 0 to 20 points)

Observations

- Weekly time of study, beyond classes, is expected to range from 4 to 6 hours.

- Informations and support material are available on the moodle web page of the course: http://moodle.fe.up.pt/0809/course/view.php?id=719

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