Teaching language

Objectives

• Learn the basics of Electromagnetism


• Derive and present the laws and methods of Electromagnetism under a phenomenological perspective


• Establish links and parallels between Electromagnetism and Mechanics, using concepts such as force and energy


• Emphasize the relevance of the concept of field in the formulation of the laws of Electromagnetism, as an entity responsible for the mediation of physical interactions


• Apply, in the context of Electromagnetism, the concepts and methods of Vector Analysis and Integral Calculus in space


• Present and describe relevant applications of Electromagnetism in Science and Technology

Learning outcomes and competences

The students will have the ability to solve basic physical situations and problems envolving topics of electrostatics and magnetostatics, and the hability to establishe links to simple experimental situations.

Working method

Presencial

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

Concepts and mathematical techniques acquired in Real Analysis I (sequences, Taylor's series, limits and continuity, differential and integral calculus) will be important for the course formalism.

The CU also makes use of the mathematical concepts thta are introduced simultaneously in Analysis II. The simultaneity of the two courses allow the demonstration/illustration of the math techniques (vectorial differential calculus) and allow a better understanding of the physical and mathematical assumptions (vectorial fields, divergence theorem/Gauss law, Stokes theorem/Ampère's Law).

Comments from the literature

The principal bibliography identifies the main references supporting the programatic topics of the course. 

The complimentary  bibliography includes alternative titles, following different approaches to the topics. Clearly, the  Lectures on Physics by R.Feynman have to be highlighted due to the physics discussion and the math approach that it uses.

Teaching methods and learning activities

Weekly Assigned readings in Perusall for comments and annotations.
Theoretical classes for discussion and clarification of assigned readings.

Problem classes for demontration of problem solving; for group activities in assigned tasks; for evaluations in individual quizes.

Eligibility for exams

To attain frequency at Electromagnetism I: 

1. Attendance of TP classees according to general FCUP rrules
   

Waiver of attendance

• 
  
  students who have attended the UC in the 2021/2022  and who have been evaluated,  may request  waive TP's classe attendance
  
  


• 
  
  Working students
  
  

Students exempt from class attendance only have access to Evaluation in Mode B (Final exam only.) They must request exemption by february 24th and should register in TP class "Dispensa"

Calculation formula of final grade

The evaluation has two modes

A: Continuous evaluation with final exam.
B: Evaluation by final exam.

Only those students who may be excused from attendance have access to mode B.


Mode  A
Continuous component: Q [0-100]: Score of 6 of 8 quizes performed in TP class;
Final Exam (Normal or remedial ) E [0-100]
Automatic Score of Perusall PS  [0-2]

Weighted grade (NP)

NP =( 0.3*Q*0.7*E)*0.2

Final Grade (NF)

NF= NP+ PS*(20-NP)/20


Mode  B
Final Exam E
Automatic Score of Perusall PS [0-2]

Weighted grade
NP = E*0.2

Final Grade
NF= NP+P P= PS*(20-NP)/20

Students who may be excused from attendance must choose whether to do so by February 24 in Moodle questionaire.
