you are welcome, and thank you for the kind words of praise. :) Keep watching, as I am preparing the next 4 videos for uploading. Much more to come. :)
I did this experiment as a child. Only I used a cork, and a large sewing needle. I would magnitize the needed with a strong magnet and then watch the cork move.
Hi Mart, I'll bet you did. And that probably kick started your lifelong fascination with magnets and magnetic devices, right? And yes, a sewing needle works fine even without the cork, as it will float on top of the water. Have you tried that one?
Thanks, Chet. The PVC for this stand cost me about $25, and the hardware was about that amount again. My bike wheel (steel 26" Huffy front wheel) was free, since it had been junked at the local recycling center. So, low cost? Yes!
The largest cost so far has been tied up in the magnets. Each of the 80 double-stacked rotor magnets was 81 cents purchased in quantity of 100 at K&J Magnetics, and my twin hard drive magnets cost $1 plus shipping at an eBay store.
great video, but, if north atract south then you miss to label that magnet. It's not N-N but N-S...
I think you need to rewrite N to S and vice versa...
Don't you?!

No, it's not a miss. Go back to video #6, and all will be understood.
