The pull and the push of the magnet and the metal cancel each other out, I think.

look it up on magnetopedia

This

You wouldn't be able to stop.

because the two objects are linked, the force of the car being attracted to the magnet will be balanced by the force of the magnet being attracted to the car

assuming the arm is strong enough to hold up against these forces, you are left with a stationary car at equilibrium; if the arm breaks, then the car will be drawn forward a distance inversely proportional to the ratio of the car's mass to the magnet's before the two objects meet and no more force is applied

What about if it was a really strong magnet?

>>1629926

then your car would implode under the magnetic forces

>>1629932

So all I would have to do is make a magnetically resistant car.

It's dead?

good luck with that

Then your magnet wouldn't pull it forward?

I'm in a situation where I know there's no chance in hell that is ever going to work, but I have no idea how to explain why it won't.

But the slab of metal is attracted to the magnet, and is attached to the car, thus pulling it forward.

FUCKING MAGNETS HOW DO THEY WORK

Seriously, though, the size of a magnet of sufficient strength would be impractical to do this on a standard sized car. The magnet would likely be heavier than the car, tipping it forward.

And the magnet is attracted to the metal by the exact same amount, pulling the car backwards because it's also attached.

If you hold metal near a magnet, the magnet moves to the metal. If you hold a magnet near metal, the metal moves to the magnet. The force pulling the car to the magnet is canceled out by the force pulling the magnet to the car.

But the magnet is held still.

I DEMAND A MINI-SCALE MODEL

Isn't the car held still? If you answer yes, then it won't move anyway. If you answer no, then the magnet isn't held still because it's part of the car.

TROLLS

The dude said he was not a troll. We are just explaining.

>>1630035
>He's not a troll, guise, he said he wasn't!

So naive

>>1630043
Adorable, isn't it?

if you grab your head and pull it up would you fly ?
