I built a scale model to prove the haters wrong. I had to tilt the platform a little for it to overcome friction, but once I did, the car rolled forward until it hit a wall.
The mount is holding the truck back. You need a wireless magnet.
Well, you used aluminum. Good work.
Because it makes the vehicle too long to park in the average garage or driveway.
Finally, an answer that makes sense.
The magnet and the metal plate pull each other, so all the pull forwards is cancelled out by the pull backwards.
Obviously, because they don’t want us to know this. Duh.
Try pulling yourself by the nose.
Ow. Now what?
Does it move you?
Not very. I prefer Mozart.
Or picking yourself up by your bootstraps.
It’s working! I’m moving!
I hit 60mph and am like 20 miles from my house. Why would you tell me to do that?
At least you didn’t pull upwards like I did. Glad the ceiling was there or it could’ve been much worse.
Magnets don’t do work
It’s cuz they got wet, isn’t it?
Less fun at parties guy: While the diagram leaves it somewhat unclear as to what precise effect that mechanism is intended to achieve, clearly it involves electromagnetism and thus any proper explanation must begin with a full description of quantum field theory…
Why not just use rope instead of a magnet? You wouldn’t need the extra metal on the front if you did that and would save weight.
What’s funny is this would actually work if you just pointed the magnet at other people’s cars.
It would only work if you manage to keep the car at an extremely precise distance from the car in front. If you’re off by tiny tiny amounts, you’ll either lose the magnetic attraction, and stop, or you’d started getting closer fast until you’d be stuck to the car in front of you
Being stuck to the car in front of you is more efficient for traffic anyways
Maybe we could make a really long car
We could chain them together and make the front car really powerful. The other cars wouldn’t even need engines!
It would get kinda hard to control though. Maybe some sort of track system could keep it steady?
That’s some crazy Elon musk idea, making a brand new mode of transport
Use to magnets of opposing polarity, the stronger magnet should be on the bumper to push the boom forward, and drag the truck with it. /s
“this would work if you did something completely different” lmao
Am I wrong? ;)
Curses, you’ve got a point…!!
Depends on what we consider wrong. Could you pull a car that way? Theoretically, yes. Could you save energy that way? No, because the car driving in front would have to do extra work to overcome the magnet pulling it towards the car behind. You can’t cheat the first law of thermodynamics.
Go (back) to school
This illustration does not imply that the car is moving. There are no “speed lines” or arrows that would indicate that.
So the illustrated setup would 100% work.
The CIA puts backdoor code in all the magnets to prevent this from working. Source: trust me bro.
It’s actually a common misconception that magnets always attract metal. This misconception was popularized by people joking that magnets are magic. In reality, magnets attract because they have magnetions in them. These magnetions allow them to attract things like metal but a little bit is used up each time. Eventually once the magnet’s magnetions have been depleted, the magnet turns back into a newt and goes home to recharge.
Can you recharge it
Science is trying to find a way, but for now you need a witch/wizard to recharge it.
