MP/PC/PSI Cours Magnétostatique (1) : sources du champ, propriétés de symétrie

The image is a little blurry for the first 2 minutes...but then stabilizes. In this first video of the magnetostatics course, we discuss the sources of magnetic fields by comparing them with the case of the electrostatic field. We study in particular the symmetry properties of the sources and their consequences on the field itself.
