The aim of the Electromagnetism Course 1 is to study electric fields constant in time, magnetic fields constant in time, and stationary electric current. More specifically, it is intended to transmit to the students the notion of field, the methods of determining the electric field, the notions of electric potential and electric energy; the notions of current intensity and current density, Ohm's law and the determination of electrical resistance, and the determination of capacitor capacities; the methods of determining the magnetic field (Ampère's law and Biot-Savart's law), the flux of the magnetic field, the vector potential, the magnetic energy and the solenoids.

Objectives
Objectives
Students must acquire in this Course Unit the following skills: determination of the electric field, the electric potential and the electric energy (for point charge distributions and continuous charge distributions with and without symmetry); determination of electrical resistance, capacitor capacity and solenoid inductance for various situations and geometries; determination of the magnetic field and the vector potential (for filiform currents and currents distributed in volume).

Assessment
Assessment
Regras de avaliação
1. Provas escritas: 70% da classificação final (PE)
2. Projetos computacionais: 30% da classificação final (PC)
Alternativas de avaliação escrita (PE)
a) Avaliação contínua
Requisitos para aprovação na disciplina:
- Média aritmética entre as duas melhores frequências (F1 e F2) igual ou superior a 10 valores, sendo as
notas F1 e F2 arredondadas à décima de valor mas iguais ou superiores a 7 valores;
- ou nota da Frequência Global igual ou superior a 10 valores;
- Nota de Laboratório igual ou superior a 10 valores.
b) Exame final
Requisitos para aprovação na disciplina:
- Classificação igual ou superior a 10 valores no exame;
- Nota de Laboratório igual ou superior a 10 valores.
Em todos os casos, a nota final será NF=0,7xPE+0,3xPC
Excepcionalmente, poderá ser realizada uma oral para confirmar qualquer nota obtida na avaliação
escrita. A nota de Laboratório inclui uma discussão individual em aula sobre os trabalhos realizados que conta 51% dessa nota.
