Introduction: DIY Simple Homemade Motor

Picture of DIY Simple Homemade Motor

This a very simple motor which is called a 'Homopolar motor'. It's a great example of how a magnetic field is produced when electricity is passed through a conductor. It is a fun project and only takes a few minutes to make.

So, let's get started!

Step 1: Materials

Picture of Materials

All you need is :

1) AA battery

2) Neodymium magnets (You can also use a couple of strong magnets)

3) Conductive wire

4) Wire cutters / pliers

That's it!

Step 2: Shaping the Wire

You can shape the wire any way you want - keep in mind there should be a tip which can balance on the end of the battery and the other end should curl around the magnets.

Step 3: Assembling the Motor

Stick the AA battery (Positive terminal up) on the magnets. Then, put the wire onto the battery and the magnets.

Step 4: The End

As soon as it is assembled, it should start spinning!

Great instructable! By the way the magnets you used were not neodimium, they were ceramic disk shaped magnets.

That's why I wrote "you could use a couple of strong magnets" because I didnt have neodymium magnets. Thanks for commenting :)
