Scientifically speaking, why wouldn't it work?

>> No.12608681

it does

Great! Energy crisis solved

It does, but you go backwards not forwards

>> No.12608692

>>12608687
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.

>> No.12608749

>>12608672
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?

>> No.12608813

>>12608672
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.

>> No.12608936

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

>> No.12608940

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.

>> No.12609032

>>12608672
Why would that necessarily propel you forwards and not backwards?
>"it does both!"
Precisely.

>> No.12609044

>>12608672
because div(B)=0

>> No.12609051

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.

>> No.12609868

>>12608672
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

>> No.12609925

>>12608672
because of the conservation of momentum

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