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 in theoretical classes, identify them in examples and apply them in the resolution of theoretical-practical exercises, justifying the results obtained.
Carrying out experimental work confers various skills on the student: autonomous acquisition of knowledge in preparing the work; use of computer tools for data acquisition and analysis; handling materials and measuring instruments; data interpretation (including statistical analysis and error analysis); personal and interpersonal skills of relationship with group colleagues and with the teacher, namely in the critical discussion of results.
The communication of science, in oral and written form, is exercised throughout the classes.
