    What cracks me up is the piece of metal, labeled metal, attached to the one metric ton of… Metal

    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.

    This illustration does not imply that the car is moving. There are no “speed lines” or arrows that would indicate that.

    So the illustrated setup would 100% work.

    So this would work actually but only for a brief second as the electrical current generated by the frame of the vehicle passing through the magnetic field would disrupt the flux conduction in the magnet. This is mostly due to being the way that it is.

      Could we fix it by constantly increasing the (electro)magnets strength?
