Hi there -
I am looking to do a "DIY" electromagnet project with a nephew. I ordered some 22AWG magnetic wire and a ferrite rod. I used a drill to wind the wire around the rod, back and forth, maybe a total of 300 winds.
Unfortunately, when I plug in each end to a battery - the battery gets very hot - and while the rod has some magnetic power, but it's fairly weak.
Are there any special measures someone should take when doing a project like this to maximize the results? Does it maybe just need more winds?
Thanks.
