Actually, I think it WILL roll. For example, 15 Lbs of magnetic pull shouldn't be any different than 15 Lbs of weight. And, hard wheels will have less friction (as long as you're not running over debris). But, the magnetic pull should (hopefully) be more than the 15 Lb weight, and the actual weight will be added to the pull.I'd say it's worthy of an experiment (maybe with one magnetic wheel, or on a small scale).
The 1st experiment should be to make sure the floor is not made from non-magnetic stainless steel.Although that's a very cool idea I have a feeling that it won't make an efficient motor.
That is great to hear! I plan on only experimenting with one wheel to see if its worth moving forward. And yes it is Steel and not stainless.
