Today we made a H
omopolar motor If you want to make one yourself you will need A battery A piece of copper wire Three or more Magnets . How to make it Place the Magnet on the battery Then make a shape with the wire place The wire carefully on the Battery And if you do it right you will find that the wire will start spinning .
We have two main players: a magnet and a wire. The magnet has an invisible field called a magnetic field that pushes and pulls on things. The wire acts as a track for tiny, invisible charged particles called electrons that flow when you connect it to a battery.
When the electrons travel through the wire near the magnet’s field, they experience a special push or shove called the Lorentz force. This force acts like a tiny sideways nudge, trying to push the electrons in a specific direction.
Hi Amelia
That looks super fun. I’ve never seen one before. Was that your favourite science experiment this term? I noticed a few capital letters in the middle of a sentence and not many full stops in your blog writing. It might be worth proofreading or getting a friend to help you check it. I loved that you told us what you need and how to make one ourselves. Maybe I’ll give it a try. What science experiment would you like to try next?
