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 guitar pickup (electromagnetic induction)

String effect on a single coil (electric guitar pickup such as those on Stratocaster). The coil is connected to a multimeter that indicates the voltage changes when the string is subject to vibration. This signal is normally sent to the amplifier.

Warning:  the voltage should reach its maximum value when the string is at maximum velocity, and not when it is at maximum displacement.
