Motors:
Motors is a very important topic in any science material, as most of the moving things you see around work on motors. Motors are very simple to understand. It amazing to think, someone initially even thought of a device that could move for ever by using electricity.
Here's a very nice video on DC motors: https://www.youtube.com/watch?v=CWulQ1ZSE3c
Motors use the basic principle of magnets and their attraction/repulsion to keep them moving for over. As shown in the video above, if magnet's polarity could be reversed every cycle, then the magnet would keep rotating for ever.
Motors are of many different kinds. We will divie them in 2 broad categories:
- DC motors: These motors work on DC voltage.
- AC motors: These motors need an AC current to run.
Simplest Electric Train:
This is based on Electromagnetic theory on which motors work. It's pretty cool to watch this.

Just amazing to even think of something like this. Let's go into the theory of why it works. FIXME
