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!
