Teaching language

Portuguese

Objectives

Present electromagnetism as a unifying model of many phenomena which are observed in nature and used in the technologies.
Develop problem solving skills, acquaintance with the mathematical tools and the mathematical language used in electromagnetism and subsequent courses.
Develop physical intuition and conceptual problem solving skills in electromagnetism.
Develop team work skills, the capacity and discipline to work continuously during the semester and an attitude of respect of ethical values, for example respect for colleagues and honesty.

Program

1) The Cartesian, cylindrical and spherical coordinate system; the transformations between systems; differentials of lengths, surface and volume.

2) Coulomb’s Law: electric charge; electric force; conductors and isolators; superposition principle.

3) The electric field; lines of force; electric flux and Gauss’s Law; applications of Gauss’s Law; the divergence of a vector field and Poisson’s equation.

4) The electrostatic potential: conservative fields; electrostatic potential; examples of electrostatic potential calculations; electric dipoles; the rotational of the electric field; the local form of the electrostatic equations; the potential of a conductor; electrostatic energy.

5) Electrostatic capacity and capacitors: method of computation of the capacity of a capacitor; examples; capacitors in series and parallel; electrostatic energy in a capacitor; dielectrics; boundary conditions for the electrostatic field.

6) The electric current; definition; charge conservation; continuity equation; Ohm’s law and conductivity; the kinetic model for Ohm’s law; wave properties of electrons; the band spectra (conductors; isolators and semi-conductors); the Joule effect; electromotive force; Kirchhoff’s laws.

7) The magnetic field: the magnetic force between currents; Ampère’s law and its applications; the Biot-Savart law and it’s applications; the Lorentz law; the Hall effect.

8) The law of induction: electromagnetic induction; Lenz’s law; generators and motors; the idea transformer; mutual and self inductance; magnetic energy.

9) Magnetic materials: magnetization currents; the H field; diamagnetism; paramagnetism and ferromagnetism; boundary conditions for the magnetostatic field; magnetic circuits.

10) Maxwell’s equations: a summary of what we have learnt so far; the displacement current; plane electromagnetic waves; energy balance and Poyinting’s vector.

Teaching methods and learning activities

Theoretical lectures: expositive lectures where the concepts are introduced and illustrated with examples and applicatons.

Recitation (exercise) lectures: problem solving by the students under the supervision of the teacher. In defined dates the distributed evaluation will take place; it will last for 30 min. and start at the beginning of the lecture.

Moodle site: download theoretical lectures power-point presentations, multimedia resources; exercises sheets; self-evaluation tests; general information on the discipline and presentation of the testes/exams results.

Office hours: personalized tutorship where doubts on the theory and applications are clarified.

Eligibility for exams

The following conditions are required to attain frequency:
- Miss a maximum of three (3) recitation classes (General Grading Rules, Art 4º, Nº 1);
- Obtain a final mark of ten (10) or above in the distributed evaluation.

The distributed evaluation consists in 4 mini-tests in pre-defined dates. Each mini-test consist in a problem from the set of problems that was previously solved [in the theoretical lectures or recitation lectures] (weight 80%) and in two multiple choice questions (weight 20%).

The frequency conditions presented above are optional for the students under the conditions presented in General Grading Rule (Art 4º, Nº 3), namely working students, military as well as the students who have attained frequency in 2006/2007.

Calculation formula of final grade

Standard students without 2006/2007 frequency:

If EF >=8 then CF = 0.4 * AD + 0.6 * EF
If EF<8 then CF = EF

where CF is the final mark (0 to 20), AD is the distributed evaluation mark (0 to 20) and EF is the final exam mark (0 to 20).

Standard students with 2006/2007 frequency:

CF = AD + 0.7 * EF

where AD is the distributed evaluation mark in 2006/2007 (0 to 6) and EF is the final exam mark (0 to 20).

Examinations or Special Assignments

n.a.

Special assessment (TE, DA, ...)

For the students that during 2007/2008 have a working student or military statute both the frequency conditions and obligatory distributed evaluation are optional.

The students in the conditions described above and that have decided to opt out from the distributed evaluation scheme or decided not to use the 2006/2007 distributed evaluation mark are admitted to exam with the final mark given by the exam mark.

The students with the “dirigente associativo” statute cannot opt out from the distributed evaluation scheme.

Classification improvement

Through the “Recurso” exam, the final mark will be computed as:


CF = MAX (CFN, 0.4 * AD + 0.6 * R, R)

where CFN is the final mark in the “Épocal normal” (0 to 20), AD is the distributed evaluation mark (0 to 20) and R the “Recurso” exam mark (0 to 20).

Observations

It is expected that students dedicate 4 to 6 hours of weekly study to the course, further to the normal attendance to the theoretical and recitation lectures.

Those students who have not attended a distributed evaluation test and have a justification accepted by the DEEC secretariat can do an extra test,

Any fraud attempt during the distributed evaluation process will lead to loss of frequency and non-admission to the final exam.
