Alt TextA screenshot of a post showing a red pickup truck with a mechanical arm structure attached to its bed, holding a magnet in front of a metal plate mounted on the front bumper, titled “Okay explain why this wouldn’t work”. Below, a comment from the official Volkswagen account reads “We sent this to the engineering department and they blocked us on teams.”

The magnet also gets pulled backwards with equal force as the plate on the front of the truck gets pulled towards the magnet.

Since the magnet is attached to the back of the truck, the base of the magnet crane is pushing back on the truck with the same amount of force it’s being pulled forward by by the plate, thus cancelling out the forces and resulting in a net of zero.

Which is why you use an electro-magnet.

You energize it, allow it to snap to the car pulling it forward slightly, then disengage it and use a motor in the arm to reset it to it's original position.

That’s way too much of a complicated system prone to wear and failure. A spring loaded pull mechanism is far more mechanically reliable and works at a wide range of scales.
