Could you be a little more specific? What values do you have? Try wikipedia, it helped me through my electricity and magnetism lab last summer. I've still kept my physics book to this day, so if you give some specifics and givens, I'll try and look some stuff up.
One of my tests showed with .8 amps run through the electromagnet held 382g. (.382 * 9.8 for force)
Electromagnet is 6 inches long, about 1020 wrappings.
Tried wikipedia and have a physics book (granted, that is beyond me, but I still think I'm finding all the equations it gives on the subject), but really the only one I can find is:
B = ((permeability of free space) (amperage) (number of turns))/unit length of solenoid
Where B is magnetic force. I can't go from magnetic force to something I can compare to how much it can hold, so it doesn't do me much good.

Dude, seriously, don't screw with me when I am deperately trying to work on equations that are beyond my comfort level. I have tried Google damnit, unless you can prove me otherwise it does not help. A bullshit response like that might make me flip out and ban you in my present state of mind.
