Scientifically speaking, why wouldn't it work?

It does, but you go backwards not forwards

Then just turn the other way
There, you're moving where you'd like to

Most people don't know how magnetism works, much less electromagnetism.

You can't just do that, all magnets are left handed, you turn it backwards you're not changing the handedness of the magnet.

you need to turn one magnet 180 deg and youre ready to go!

Magnets are bi-directional force always pushing in both directions...

Why ypu need machine as such?

Because the magnets pull on each other with an equal force, meaning that the front magnet is being pulled backwards just as much as the back magnet is being pulled forwards and thus you don't move.

1. They're apart of the same system (the car).
2. That's it! I don't fuckin' know.
Maybe the fact that both magnets are acting on each other won't allow them to move. Maybe you need both a stronger magnet and a different system acting.

Internal force(s) can't change the linear momentum of a system. That's why it won't work.

OP, be an empiricist and give it a try.

Look at a magnetic train. The train is mobile. The rail is fixed. It moves because of the magnetic force. It wouldn't move if both rail and train were pieced together.

Why would that necessarily propel you forwards and not backwards?
>"it does both!"
Precisely.

magnetic force is no different from any other force so yes it can be used to move things, you still need energy though

No it wouldn't work due to Newton's third law of motion, what you need instead is to replace one of the magnets with a iron block this will cause only one magnet to push (or pull) and move.

Because both magnets are attached to the cart, and are therefore part of the same closed system. Since every action has an equal and opposite reaction, the magnets apply a net zero force on the cart

I hope this hasn't been patented. I'm stealing it.
