Hello!
I'm doing a science fair experiment (it's a class assignment) and wanted to do something that has to do with electronics. It can be very simple, it must have a few variables, though (ie: 1.5V, 9V voltages). If you guys have any ideas or have done an electric experiment in the past for school, please tell me your ideas. This is for the eighth grade, so it doesn't have to be anything very fancy.
What I though would be really cool (but I probably coudn't get it to work) was to somehow 'levitate' small discs of metal (a round magnet would probably do the trick best) and create an electromagnet which repels the side of the magnet with the same charge. The way the disc would stay in place would be a clear cylinder which allows it to go up, but not out of a small radius of space. The variables would be the different voltages used to repel the magnet. For example, a 9V battery would repel it more than a 1.5V.
If you think this has a chance, tell me. If not, that's OK! But any other ideas would be appreciated.
