What is the strongest commercially available electromagnet that I can buy (or build)?

Besides superconductors, electromagnets are limited to the saturation induction of the core, about 2.1T with plain soft iron. Only the size limits the force, but there is no hard limit on the size but your budget, as Swansont pointed out. Electricity consumption and cooling aren't a huge issue.
