Eletromagnetismo

Mathematics: Vector calculus, differential and integral calculus, orthogonal coordinate systems, differential and integral operators.

Physics: Kinematics, particle and rigid body dynamics, work and energy.

Theoretical classes where a theoretical exposition of each content is made, containing a brief historical review and many application examples.
In the theoretical-practical classes, exercises will be solved for the application of the subjects taught in the theoretical classes. Critical analysis and discussion of the results obtained will be encouraged. Complementary exercises for resolution outside of classes will be proposed.
In laboratory classes, students carry out practical work in small groups, under the supervision of the teacher.

In this Curricular Unit, competences related to the understanding of Nature in the field of Electromagnetism will be acquired, with emphasis on the most technologically important concepts.
The student must assimilate contents presented, identify them in examples and apply them in the resolution of theoretical-practical exercises, justifying the results obtained.

Assessment by final exam, with a minimum mark of 9.5.

Students who have successfully completed the laboratory component in the previous two academic years may use it. In this case, the laboratory component, P, has a weight of 4.00 and the final exam, E, has a weight of 16.00, with the final grade being given as C=P+E. The student passes if C is greater than or equal to 9.5.

The compulsory or optional final written exams are those set out in the ISEC's regulations.

During the exams, no electronic device may be used, nor may any item be consulted except for an A4 sheet of paper with arbitrary content. The use of a non-graphical calculator is permitted.
