I'm having a presentation about dc generators and I wanted to demonstrate how it works. Anyone have an idea on how to build one. I left my electric motors at home because of Christmas break, now I can't find anything.

For a presentation it might makes sense to reproduce one of Faraday's original experiments which give more of a visible insight into what is going on than a modern generator which is essentially just a sealed box.

Something like the experiment in this video would be quick and easy to set up.

Obviously making a rotating armature which produces a steady current is a bit more difficult than just moving a magnet in and out of a coil but in some ways the simple version demonstrates the underlying concept better.

  • $\begingroup$ It is certainly possible, it helps that very powerful magnets are now fairy chap and easily available youtube.com/watch?v=gZpa7FYR_pw $\endgroup$ Jan 6 '17 at 13:43
