Michael Faraday's famous apparatus - video link

[ee851]

If you have studied electricity and magnetism, you will recognize the name Michael Faraday.     

This morning I found this video.    It contains the simplest explanation of  Michael Faraday's observations that I have ever heard.     Well, it seems simple now.    Was quite a revelation in his time, no doubt.

The modern apparatus in the video is even more impressive.    Thought you might enjoy a look.
