I need to make a laboratory electromagnet that can produce an induction of ~1T over a 1"x1" area with an air gap of about 1" .
I have a small budget ~$1000. Which is why I think I'll have to make it. Can somebody give me a few pointers on what iron I should use? I know it should be of lowest carbon content as possible, but I'm afraid I won't be able to find low carbon iron at an affordable price. What commonly available steel could I use in it's place?
Also has anyone wound a coil on there own without a winder? How much should I expect to pay to have a coil wound?
Thanks for any ideas
