Welcome


The title says it all: this blog features physics videos found everywhere on the web: animations, demonstrations, lectures, documentaries.
Please go here if you want to suggest other nice physics videos, and here if I mistakingly infringed your copyrights. If you understand French, you'll find a huge selection of physics videos in French in my other blog Vidéos de Physique.

Electric flux

The electric flux is proportional to the number of electric field lines going through a surface. This animation illustrates the 3 parameters influencing the electric flux: the area of the surface crossed by electric field lines, the magnitude of the electric field and the angle between the electric field and the surface. In the animation, the electric field lines are green when they cross the surface, and become yellow when they don't cross the surface.
