MakersHourQuestionsQ1: Hello. Some of us have created some very strange things over the years, what’s the strangest (for you) thing you have ever made? #MakersHour
Eivind@MakersHour As a teacher, I once was about to do the the magnet-and-iron-dust-on-paper experiment with my class, but discovered too late that we didn't have a magnet! What we did have, though, was a copper coil, some rusty nails, and a battery. I put the nails inside the coil, connected the battery and got the nails *just* magnetised enough to do the experiment and show the magnetic patterns. I made a magnet.

That is a very good way around it, and shows other electromagnetic principles at the same time.
I noticed and photographed this in my workshop a while ago, while I was welding.
