Okay. Could I place permament magnets under the steel, instead of electromagnets, and if I do so, if I want the magnets I have on my person, would it be fine if the magnets under the steel were of weaker pull force, aslong as they are secured?

Yeah, haha, I have thought about getting another material. Will Iron work as I want it too though? I want to be able to switch it from attraction to repel. I've punched in some numbers, and in theory, it's possible, and will be a steady lift. The current will be coming from a source on the my shoes, so it should be fine. The total magnetic force, with my weight taken away is 110 pounds extra. Some of that will be lost to energy loss and such, but should still provide enough "umph" for there to be lift.

Thanks!!!

Hey, this is actually a lab I am designing, and I've run into a few problems that I can't seem to figure out. I will be having 4 neodymium magnets attached to me (2 per shoe) with there being a switch to allow/turn off an electrical current to the magnets. I also have a sheet of steel, which I will step onto. Now, when I step onto in, the magnets will be attracted, but when I flip on the current, behold they repel, and propulsion is created. My problem is that, in designing I overlooked the fact that, normal steel, will attract both poles. Which puts a major kink in my plan. I was wondering if anyone knew any techniques to make the steel act like a magnet, with the ability to attract/repel? Thanks!
