Objectives

Intended learning outcomes of the curricular unit (knowledge, skills, and competencies to be developed by the students):

The Physics II course aims to provide students with operational knowledge in magnetism, circuits, materials and magnetic devices, waves, and optics, which are fundamental areas of expertise for contemporary engineering. The electromagnetic and optical behavior of materials have a growing technological utility.

During this course, students will:

1. a) develop physical intuition by discussing and analyzing situations of electromagnetic nature observed in nature and used in devices, identifying the physical laws governing them;


2. b) model these situations, using approximations and analytical and numerical tools, with critical sense.


3. (c) to measure in the laboratory electromagnetic, wave, and optical quantities in various situations with a critical sense compared to model predictions.

 

The curricular unit is essentially integrated into the descriptors “1. Scientific-Technical Knowledge and Reasoning” and “2. Personal and professional skills” of the CDIO (Conceiving - Designing - Implementing - Operating) quality system. In particular: a) “1.1. Basic science knowledge”; “1.2. Nuclear Engineering Knowledge (Engineering Sciences)”; c) “2.1. Engineering thinking and problem solving”; d) “2.2. Experimentation and discovery of knowledge”. The descriptor “3.1. Group work” of “3. Interpersonal Skills”.

At the level of the EUR-ACE quality system, the curricular unit fits essentially with the descriptor “Knowledge and understanding” and, to a lesser extent, the descriptors “Engineering Analysis” and “Communication and Teamwork”.

Learning outcomes and competences

Learning outcomes of the course unit. At the end of the course unit students are expected to:

1. a) Describe the quantities, concepts, and physical laws governing electromagnetism, circuits, materials, and devices with special magnetic properties, waves, and optics, with mathematical rigor, making correct use of scientific vocabulary and identifying domains of validity.
2. b) Build circuits and measure electromagnetic quantities (capacitance and inductance) and wave and optical properties of laboratory materials, making use of multimeters, oscilloscopes, lasers, and sensors, estimating errors associated with measurements, being critical in relation to the results obtained and respected. laboratory safety rules.
3. c) Model the magnetic field in simple situations, and calculate self-inductance and mutual inductance. Describe magnetic phenomena in different kinds of materials (e.g. diamagnetic, paramagnetic, ferromagnetic, antiferromagnetic, and superconducting materials).
4. d) Work in groups, organizing and sharing tasks, executing and justifying the steps taken in their task, and listening critically to the justifications of other group members in relation to their tasks.

e) Assume a working posture respecting ethical values, developing a continuous study throughout the semester, and verifying the learning through self-assessment tools and feedback from the teacher and fellow students.

Evaluation Type

Distributed evaluation without final exam

Assessment Components

Designation	Weight (%)
Teste	70,00
Trabalho laboratorial	20,00
Participação presencial	10,00
Total:	100,00

Amount of time allocated to each course unit

Designation	Time (hours)
Estudo autónomo	53,00
Frequência das aulas	56,00
Total:	109,00

Eligibility for exams

 

Students obtain frequency if:

- Do not miss more than 4 recitation classes;

-Students with more than 4 absences cannot pass the "recurso exam".

- Obtain a mark of 10 valores in the continuous evaluation.

Calculation formula of final grade

The evaluation consists in:

- TI: mid-term test;

- TF: final test;

- AP: evaluation of the participation in the TP;

- AL: evaluation of the participation and lab work

 

The final mark NF is given by the formula and the student is approved if his/her mark is >=10 :

NF=0.7((TI+TF)/2) + 0.1AP + 0.2AL

 

Examinations or Special Assignments

n.a.

Internship work/project

n.a.

Special assessment (TE, DA, ...)

For the students who have a working student or military statute during the present academic year, both the frequency conditions and obligatory distributed evaluation are optional.  The recurso exam might have a laboratory component.

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

Non-portuguese speaking students will have classes in English. The group laboratory component of the final mark will be kept.

Classification improvement

Through the “Recurso” exam, which might include a laboratory component.

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 practice classes
