# General physics: electromagnetism

## Summary

The topics covered by the course are concepts of fluid mechanics, waves, and electromagnetism.

## Content

**Concepts of fluid mechanics**

- Statics and dynamics of ideal fluids**Waves**

- General understanding of wave motion, including energetic aspects

- Description of different waves propagating in a dense medium

- Electromagnetic waves, Poynting vector, energy considerations

- Superposition of waves: reflection, stationary waves via interference**Electromagnetism**

- Electrostatics: Coulomb law and electric field, Gauss law, electric potential, capacity and energy, electric fields in dielectric matter

- Electrical currents and AC circuits

- Magnetostatics: electric current and magnetic field, the two fundamental laws, magnetic properties of matter, ferromagnetism.

- The Faraday law: the electromotive force, the law of induction, self and mutual inductances, the magnetic energy

- Maxwell equations: the displacement current and Maxwell equations in vacuum and materials

## Keywords
