force diminishes with the cube of distance.

F=1/d^3.

This makes for very little force as distance increases.

Yes a magnet can attract objects over distances farther than one meter. As they used to say on the most amazing show of all time: "If it's worth doing, it's worth over doing

For what reason, and in which direction?

I keep thinking of a several coils, each with a diameter of two times the distance you want to lift with a hefty current in one capable of more then holding and the other pulsed by capacitor with an initial 20X times that holding current to start.

Of course in space it wouldn't take much.

BTW, There are stars that would take the central iron out of your blood cell at a million miles away...

Go to a big scrap metal joint or car wrecker.
Check the magnets they use to lift cars and other things - that is still too small for your purpose.
I think you get the picture and will decide to grab the steel ball by hand instead ;)
