For the same reason why this device does not go left by the metal slab pulling the magnet to the left

Mythbusters did a similar one using a fan and a sailboat. The boat moved. Backwards.

That one worked because it was just an inneficient way of pointing the fan backwards, the center of mass, as the average of the position of all the mass doesn't move from inside forces, just outside ones, so for the car to move the mass of the magnet and arm would meet to move in relation to the car, because they can't, the car doesn't move too.

Wich is basically just a long way of saying "Newton laws".

It will work fine of your intention is to secure the arm so that it won't dangle when you drive

Jim Knopf und Lukas der Lokomotivführer (Jim Button and Lukas the Engine Driver) dit it first:

They even got one step behound: The two rocks you see in the drawing are actually a broken up magnet into it's north pole and south pole, so it's only magnetic when they connect the both with a metal rod. Genius. (ofc that's EXACTLY how magnets work)

There are magnetic monopoles, but only in quantum physics.

I also find it funny how i got introduced to the troll physics meme 20 years before it was called that, as a small child back in the 90s

Magneto was right!

I think that only works on steam trains

It's basically the same problem as the sailboat with a fan.
