This looks like the magnetic version of pulling yourself up by the bootstraps.

The car is also made out of metal. Why do you need the metal in front?
More weight = more magnetic
I don't know.
The actual metal content varies. With plastic bumpers, aluminum condenser/radiator, composite support pieces, the actual amount of magnetic metal may be quite minimal, and there's practically no vehicles that have so much metal in their front end to compare to a slab of metal on the outside.
Try using a magnet on a can of coke.
"But it's made of metal" he says.

Because the hand brake is still pulled, dummie
Issac Newton would like to have a word.
He's dead
You dont wana mess with zombie newton.
Your post infuriated him so much he came back to life to yell at you for this monstrosity
That must be why my magnet car is not moving.
Archimedes once said something like: "Give me a big enough lever and a place to stand, and I shall move the Earth."
The "place to stand" part is just as critical as the lever part. You gotta have something to push off of in order to move other things. This is a closed system that pushes and pulls only against itself.
Back where I'm from the elders used to call this kind of thing "bait for social media interaction"
Where I'm from this exact picture was easily recognized as a funny joke
Well where I'm from they call it artificially elevated social attraction
Simple. The magnet weighs less than the car, so the magnet is going to be moving to the left. If the force is going to the left, that means the car can only go in reverse.
So the vehicle just needs turning around for this to work then or.....?
Nope, unfortunately now the car has been magnetized, and that would swap the polarity, making it move in the opposite direction, which is reverse again.
I am a complete idiot and I would also like to know.
The magnet pulls the truck to the right. The truck pulls the magnet to the left. They both have the same amount of pull. No one wins this tug-o-war.
The best you can hope for is for the truck to move slightly to the right and the magnet to move far to the left until they meet
Because the magnet is attached to the truck bed, so the bumper is being pulled forward and the bed pushed back, and the forces cancel out to 0.

Newtons laws of motion, most clearly the third.
"If two bodies exert forces on each other, these forces have the same magnitude but opposite directions."
In simple terms: metal is just as much attracted to magnet as magnet is to metal, this is fundamental and doesn't change under any circumstances.
So the force driving the car forward is exactly equal to the force driving the car backward, and you can't have one without the other.
The truck will be attracted forward towards the magnet, but the magnet will also be attracted backward towards the truck with equal force. The backward force will be transfered through the arm holding the magnet and the net force on the whole system will be 0. If there was no arm holding the truck and the magnet apart, the truck could move forward slightly and the magnet could move backward to meet it. (The magnet would move much more than the truck since they would still have equal force applying to them, and the truck's mass is much higher than the magnet's.)

Because the truck wouldn't be loud and obnoxious so no Truck person would ever drive it

This is basically how you build a warp drive in Kerbal Space Program
docking port attraction force lmao
Newton’s third law would like to have a word with you 🫠
Why put metal in front of a car that‘s made out of… metal?
go faster
The force pulling the car to the magnet is the same as the magnet pulling towards the car. These two forces cancel out each other.
Ok one reason… physics.
Why do you put metal on front? The car is already metalic
Draw a force diagram. Then bing perpetual machines.
Conservation of momentum
It would in the same way a boat with a fan on it would
A boat with a fan on it can work, because that air bounces off the sail and ends up going backward
In that way it does not. You can move a boat wirh a fan if you use it to blow the air away from the boat to create thrust like a plane. If you direct the fan onto the sail the force of the forward motion will be canceled out by the backwards thrust (if the sail has 100% efficiency which it does not)
