Look at it this way though: the momentum that gravity needs a 100 feet falling distance to gather, will be stopped by electromagnetism in a millimeter.
Well, I suspect even electromagnetism will need quite a few more than one millimeter to stop a body that has fallen 100 feet.

What will you think of gravity when you fall? Will it be Meh !!! ?Set up properly, it would probably work quite well. Have you tried pushing two Neodymium magnets together or pulling them apart?
That's how maglev train works. Permanent neodymium magnets working against electromagnets.
