### Course description and aims

This course teaches the basics of static electric and magnetic fields in vacuum, starting with Coulomb’s force law for charges.

Electromagnetism is important for understanding nature, and is essential for the study of science, engineering, life sciences, and other specialized courses. Students will understand how charges and current produce electric and magnetic fields, respectively, and their mathematical descriptions. This will allow them to understand static electromagnetic phenomena as well as allow them to solve basic problems in electromagnetism.

### Student learning outcomes

By completing this course, students will be able to:
1) Understand the concepts of electric field, electric potential, electrostatic energy, magnetic flux density, magnetic moment, etc., correctly, and describe them mathematically.
2) Understand Gauss's law for electric fields and the Biot-Savart law for magnetic fields correctly, and find the electric field and magnetic flux density by applying said laws.
3) Find mathematical solutions to problems in electromagnetism expressed by the appropriate equations, and explain the physical meaning of said solutions.

### Keywords

Coulomb’s law, electric field, Gauss's law, electric potential, conductor, condenser, capacitance, electrostatic energy, electric current, magnetic force, magnetic flux density, magnetic moment, Biot-Savart law

### Competencies that will be developed

 ✔ Specialist skills Intercultural skills Communication skills Critical thinking skills ✔ Practical and/or problem-solving skills

### Class flow

Two-thirds of each class is devoted to fundamentals and the rest to advanced content or application. To allow students to get a good understanding of the course contents and practice application, problems related to the contents of this course are provided in Exercises in Physics II.
