How to Create a Homopolar Motor

The video is about how to create a simple homopolar electric motor at home. It’s really easy to do, and you will not need any professional material or stuff to do that at home.

The video is about how to design a simple one, you can also create your own homopolar motor with some creative design.

Before we get started, you will need a piece of copper wire (or Aluminum wire). I will be using copper wire here. The wire should be longer than 15 cm or 6” (which is 3 to 4 times the length of an AA battery). The diameter should be larger than 0.4mm and smaller than 1mm. You will also need a new AA battery and several small neodymium disc magnets (which should have a diameter less than 1 cm, magnetized through thickness). It shouldn’t be more than 1 cm thick. I will use 5 small neodymium disc magnets obtainable from Stanford Magnets. Okay, let’s get started so first you will need to bend, the copper or aluminum wire into an oval shape. It can be a little bit tricky, so you might want to use pliers. You need to make sure the ends are bends a little bit and also make sure that there is a hoop in the center. Ok, it takes some time to bend. So here is one we already made earlier. So as you can see, there is an oval shape with 2 bends and hoop. And then you need to place the neodymium magnets first, followed by the AA Battery with the negative side and then place the copper wire in the center. And then, it will begin to twirl. Well, you need to make sure it’s in the center. And then, you have a homopolar electric motor.
