Most powerful electromagnet/magnet for hobbyist?

[Sven Andersson]

What is the most powerful electromagnet/magnet that a hobbyist can afford to buy? That is, the one that can generate the strongest field? Are superconducting magnets prohibitively expensive? Really powerful lasers can be bought on the Internet, but I have never seen a store for electromagnets. Is there one?

I would say, check out this thread. But as it turns out, that's a question that you asked. And didn't stick around for the answer.

Volume? Uniformity of the field?

This is nice, I think:
