Thanks jacquesm! The more I look into the problem, the more challenges I'm finding. A friend of mine did this for his master's thesis back in 2002, so I know it's not impossible, but he had a strong background in EE (whereas I'm a relative n00b). Also, thanks for the search query. I'm checking on it now.

It's almost a perfect storm of inconvenient equations. Magnetic field strength drops off as the cube of the distance, so you want to increase the current in the coil, but power loss (and thus heating) in the coil goes up as the square of the current, while field strength is only linear.
