Homopolar Motor

My Grandaughter is staying with us for a few days and doing some science and technology.
Here we made a Homopolar motor.
We used a very fine wire attached to the main wire to make the electrical contact to reduce friction. You have to look very closely to see it.

Generally my projects are for my grandchildren to enjoy. OK, I enjoy them too. If anybody else likes them, that is a bonus. I like to keep my work as simple and basic as possible so that it can be copied easily and improved by anybody who wants to try themselves. I recycle or repurpose items rather than buy new and when I do buy I like to keep it cheap.
