You had me worried for a second there. At the start I was like "the internal force is still zero, it won't move", by the end the "dramatic tension" had me worried that I failed my physics teachers and professors.
It’s pretty easy to understand why it doesn’t work if you think that the front magnet is pulling the other forward as well as the other is pulling the front magnet backwards. it took me a while to process it. Thanks for showing us the truth behind the meme car :)
ok this is gonna sound dumb but instead of the magnet on the car, replace it with a slab of pure iron? iron doesnt have its own pull, so it could only theoretically go forwards right?
I feel like the answer was quite obvious, but it was still very interesting to see you build it and explain it in a more scientific way! Great video :)
@@neocirus115 Well yeah, but the arm is on wheels along with the rest of the vehicle. You've explained part of the reason, the other part being that each magnet is attracting the other, in opposing directions. Not just the front magnet pulling it forwards. So there's no net force from the magnets making the car move either way.
It's obvious if you take a minute to think about it, but I understand. This is cool! The problem is a magnet that can't move won't move if the magnet it is attracted to isn't able to move either. This car is no different from holding two magnets next to eachother. It would work if the second magnet was moving individually from the car, but it defeats the purpose of it.
Basically the arm can't move the car unless the arm is MOVING individually of the car. Not necessarily completely seperate from the car, just moving seperately.
The world is science! Everything runs on scientific principles and there's never been 5 minutes where it didn't. For cavemen to figure out stuff like wheels, levers, blades, ropes, they'd have needed to pay attention to the world around them, detailed attention. Then build models in their heads of what was going on, so they could figure out and master that particular thing. Same with farming, we had to figure out how to stop animals from running away all the time, rather to just sit around eating grass and getting fat, then when it's time to slaughter one, we take it round this corner here so the others don't know what's happened. All science. Some apes can do it, to a certain extent. As can crows, bizarrely, they act way more intelligently than other birds of their size and brain-size. Maybe all birds could do it, but only crows have found a need to, or crows pass it down socially through instructing their young. Lego's a great toy for testing scientific principles. It's partly why Technic exists. Average kids can have their play-house or their space battles or H---- P----- or whatever, those with the scientific and engineering gene can play with Technic and end up inventing some machine that's gonna make them rich in 20 years time. There's some amazing UA-cam videos where somebody demonstrates, say, 20 different types of machine, or gearbox, or principle, or whatever. All in Technic. The stuff is amazing, and I think way past the original idea that Hålværd Lêgø had when he invented tiny house bricks to encourage women to take up masonry.
You know what the most satisfying sound and satisfying thing of lego?, Its when you hear the clicking of lego pieces going together and when you finally complete a lego build and finally putting it on display for your friends and family to see.
another potentially useful explanation: the magnet on the car is pulling the car forward, but the magnet on the arm is still connected to the car so its pulling the car backwards
Well, yes but actually no. The two forces would cancel each other out that is true. However, neither force is acting on the car's wheels at all. Even if you somehow increased the magnetic force on one side it still wouldn't move the car. It would snap the frame before the wheels ever moved an inch. All of the applied forces would be acting internally on the frame of the car. None of it would ever be converted into external locomotion.
Rebuild this with a different design When you tested it at the beginning 1: you didn't have all that added weight 2: you had it behind the front wheels So build it with the magnet behind the front wheels and hold the second magnet and reduce the weight by testing how much weight the magnet can pull
ngl i thought he didn't know it wasn't going to work, and I was concerned for his mental wellbeing. turns out he was just making it interesting and suspenseful
Two magnets are connected to the same point on the object (lego car) so they cant pull eachother because they centralize the power between them too so they just pull themselves "inside". If the other magnet is connected to another stable point in the space it makes the other magnet move to it because its stable, as you know, two positives connect . The human holding the magnet is a stable point that does not move (cannot be moveable by the magnet on the car because the car is less stable in space than the human holding it) so the car will not move the other magnet, then it will move to the other magnet. If the magnet connects to the same object, in this case there are two unstable points that can be moved so they cant do this. If somehow in physics there was a way to make "stable" but unstable point in space it would be possible. Its like pulling an excavator that is pulling the other excavator. They would just.... Crush themselves down like the magnets magneting themselves to the center. It appears to be connected with the mass of the object (AND POWER OF THE MAGNETS). If the car weighted more than the human, the human would magnetize to the car because the car is MORE stable than the human with magnet. Thats is how I explain it, dont write comments if I did something wrong.
You can actually made a magnet car if you use circular magnets as the wheels and other magnets to pull them, because it’s not pulling anything it’s just spinning the wheels so it moves. The problem is, it only rolls for a little bit and then it stops. And the never bigger problem is that even if you got it to run “forever”, it’s still not perpetual motion because magnets lose their magnetism over time.
That's what an electro magnetic motor is. To make it work, you have to constantly turn on and off the magnets, so they don't get stuck. Since this requires an external energy input it can't run on it's own. It would take maybe a hundred or more years for an electro magnet to lose it's magnetism. But even if a magnet wouldn't lose it's magnetism, you wouldn't be able to build a mechanism that relied only on the magnets to power the wheel.
@@Into_Ingrid Electro magnets never loose their magnetism as it's the flow of electricity producing a magnetic field around the coil & not the innate magnetic capabilities of the material.

I knew it wouldn't work and the way you explained it is how I would've explained it if I were better at explaining things! Great video! You just got a sub as well!
They attract eachother... not the car... I recon if you made a car that shoots / dispenses a magnet forward and if the magnet has enough weight / friction then it would pull the car foreward if the car was light enough with minimal friction and a magnet on the front then as the car reaches it the car picks up the magnet (mabey the magnets switch polarity and repel or move outta the way) and car then dispenses another magnet and it goes on FOREVER... (theoreticaly) ok... kinda a bad idea... mabey invest time in something else... but ya never know! ALSO... epic explanation! Laws of motion are the best!!! Also I kinda diddent watch the vid as I spent all that time writing this!!! If you read this... THANKYOU SO MUCH!!!
Most magnets are capable of wiping floppys, but very few can affect hard drives and most modern storage is solid state, which is not at all affected by magnets.

Even with magnets, the "perpetual motion" will run out because magnets will loose their magnetism. It may take 100s, 1000s, or 1,000,000s of years for them to fail, but they will!
The fact that the hole in the wall stays there makes me question whether or not he actually put a hole in the wall and decided to make a skit out of it
My theory of its failure is that the north and south ends repel from each other, therefore its cancelled out as one end wants the car to go backwards, and the other forwards. On the other hand, if they were the correct way, and that distance apart, the magnets will want to attach and then propelling the car either forwards and or backwards
If you didn't understand the explanation the reason it doesn't create perpetual motion is because magnets pull both meaning they are both pulling on eachother canceling Amy movement out like if a tug of war is perfectly balanced, there is equal force coming from each side, but once on magnet is held stationary and the other one can roll the forces are no longer equal because you are holding on still. Mike drop
The example of using magnets to fly to outer space is the best example. It is so dumb down that should shut up all those theory crafter that made that original car idea xD
The magnets don't cancel each other. They are simply attached to the same frame of reference and thus no force is applied. It's like trying to move a sail boat by blowing on the sail while standing on the boat.
@@exotrrc1636 It doesn't lol, a person themselves wouldn't be able to overcome their weight with blowing, but you can sit in a wagon with a leaf blower and umbrella and see that you can apply the force against the sail using an item in your craft.
I had to make a gadget that used magnets to move as an assignment a few years ago, and I basically just made this, except it was a pair of shoes. I somehow did not realize that this would not work until after I submitted it. I got an A on that assignment.
i mean its more like the lift that would pull you up is equal to the force holding you down by the magnet, weight aside. horizontal propulsion is equalizing basically. its a 1 = 1 situation
i saw the thumbnail and went “hell no why u think this gonna work” cuz the magnets are just going to attract to eachother, not just one attracted to the other
You can create Nigh Prepetual motion, if you make a Forced Oppositional Magnetic drive.... which is a highly deceptive term for... you have 1 magnet in the middle, that is stuck to a big gear, and several smaller magnets on smaller gears, as it turns, it forces north to north thus forcing the gear to turn... and as the gears turn, more magnets go north to north... or something to this effect.
Yeah but what if you make another car with a magnet on the back an put it in front of the truck with te magnet on the front so both can move each other (It's just a funny request, you should try it xd)
Magnets can only wipe electronics that rely on magnets to store data. Electronics using only SSDs these days are safe from magnetic interference. It's why phones can use magnets in their cases to detect if the case is open or closed.
Im pretty sure it works if you have a magnet on the front of the truck, and a piece of metal on the crane, I have tried it before and got it to work somehow.
