Class Electromagnetism I

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.
