William Sturgeon was born on this day in 1783. He was the first physicist to wrap a wire around a piece of metal to produce an electromagnet. Thinking about it, I think this might be the first scientific experiment I tried. I made hundreds of these and devices made from them as a child. I used dynamite wire wound around a nail and hooked up to a switch and a model train transformer. You can make so many things out of an electromagnet.
