IBPH Episode #9 - Electromagnetic induction

This episode is an introduction to electromagnetic induction. The presentation is supported by many experimental demonstrations.

The video covers the following topics: 1. Oersted’s discovery of the magnetic effect of an electric current (sometimes called the “motor effect” as it is the principle behind simple DC motors); 2. Faraday’s discovery of electromagnetic induction; 3. Magnetic flux; 4. Flux linkage; 5. Faraday’s law of electromagnetic induction; 6. Lenz’s law (or Lenz’s rule); 7. Eddy currents and their braking effect.

Rube Goldberg Machine

A Rube Goldberg Machine always features a lot of physics...

The official video for the recorded version of "This Too Shall Pass" off of the album "Of the Blue Colour of the Sky" by OK Go. The video was filmed in a two story warehouse, in the Echo Park neighborhood of Los Angeles, CA. The "machine" was designed and built by the band, along with members of Syyn Labs over the course of several months.  Directed by James Frost, OK Go and Syyn Labs. Produced by Shirley Moyers.

Light bulb filament

Bill Hammack takes apart an incandescent to show how the tungsten filament is made. He shows it in extreme close-up and also discusses the material processing needed to produce ductile tungsten.
