MarkT:
But you have ones about to contact the floor pulling you forward to balance out the
pull from the ones leaving the floor at the rear. If you had flexible magnetic strip for the tracks
that would be even better.
That's why you turn off the coils leaving the floor so there is no pull in the opposite direction?
I may have misinterpreted what you meant to say there.
MarkT:
but more flat area with magnets is automatically
more total normal force.
This is why I am thinking the smaller the coil, the more chance of it being flat, i guess you could say. Its like trying to make the coil closer to a single point so it makes flat contact at the single point on the floor, if that makes sense lol. I understand I wont make flat contact with the floor, but I'd like to try it out.
