    Fun at partys guy: While the car will actually experience a force torwards the magnet, so will the magnet experience an equal amount of force torwards tha car. Given the connection between the car and the magnet is stiff, these opposing forces will stress the connection and create a reactive force in there according to Newtens 3rd law, ultimatly canseling the forces out and neither the car nor the magnet will move.

    If you however remove the stiff connection, the car and the magnet will move torwards each other untill they meet.

      what if you just attach a second magnet to the car so that it pulls the first magnet forwards?

      How about if you launch a huge magnet well above escape velocity and remotely anchor a space elevator made from a ferromagnetic material to it but the space elevator’s weight counteracts its inertia exactly and holds it in place perpetually. Would that work?

      Edit: I swear I’m not dumb, I just didn’t think this one through.
