Electrical Generator Animation

For many years I had an electrical generator animation in my webpage http://www.generatorguide.net/howgeneratorworks.html , which explains how generator works. That animation was courtesy of Joe Wolfe at Physclips Project at UNSW. The problem is, it was in swf format which requires Flash player. As we know, Adobe will stop supporting Flash after 2020. As the result, then most if not all web browsers will no longer display Flash videos. You already see this message when you open Chrome. So, I've converted the Flash animation into mp4 video. There are many generator animations on the web, but this one will work beyond 2020.
