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.

Motion of Electric Charges in a Uniform Magnetic Field

This animation portrays the motion of an electric charge in a uniform magnetic field. Starting with the special case where the initial motion is perpendicular to the magnetic field, we see that the motion is circular. The frequency of this circular motion (the cyclotron frequency) does not depend upon the speed of the charge. When generalizing the charge's motion to the full 3-D case, we see that the charge's will spiral along (and around) magnetic field lines.
