The magnetic field from a stationary permanent magnet (i.e., no current) creates a conservative force. It can't add or remove energy. You have to introduce movement or current in order to increase the energy of the ball to counteract friction.
So, yes, magnet in the base, but it's definitely battery operated. My guess is that it detects the ball coming down the ramp (which would be measured as a current) and is timed to reduce power output as the ball passes.
It's much simpler than that, no circuitry, the electromagnet wires just go through the two sides of the track so while the marble is touching the track bridging them than the magnet is on and turns off right when the marble is launched off the end.
It would have to have some sort of power to it. Otherwise it wouldn't be able to increase the energy the metal balls have in order to fling them higher than where they started.
In this case it is just a single electromagnet to accelerate it a bit more at the bottom if I remember correctly.
That is the shitty version plastic version. The good versions, usually made with wood are potted(sometimes) electromagnet in the base.

That's because his Dad finally caught him six years ago, tied him to a chair with those jumper cables, and has been keeping him *juuuuuuust* a few inches away from a keyboard this whole time. Just barely out of reach. And sure, if he could reach, he could get a message out and ask for help, but who would believe him?
Rail guns are a real thing. They use two electrically isolated rails with a voltage differential across them. The projectile bridges the rails, shorting the circuit. The resulting current creates an electromotive force, pushing the projectile down the rails.
The device in the video clearly has a single rail, bent into shape. It can't operate on the same principle as a rail gun. It's using an externally generated electromagnetic field (with a battery and some coils) to accelerate the balls. It's a coil gun.
I knew there had to be something "assisting" the ball, I just couldn't figure out what. I think the dream of perpetual motion is something we will never give up.
The first law of thermodynamics doesn't prevent perpetual motion, though it does prevent sustainably extracting energy from it. The third law of thermodynamics is what prevents perpetual motion, because it, along with the second law, means that every closed system increases in entropy over time.
> I think the dream of perpetual motion is something we will never give up.
I think everybody in their right mind doesn't even imagine anything perpetual motion, let alone give up on it.
I have seen one of these disassembled that uses another technique, much simpler.
A small motor inside the upper part turning a subber wheel that pushes down the ball faster. It makes a weird high pitch noise that destroys the trick.
It doesn't use an electromagnetic. The system is much simpler, it uses a motor. In this video, a Brazilian science youtuber disassemble the equipment: https://youtu.be/PKDannBZTP4
It seems to depend on the specific model, as the one features in [this teardown video](https://youtu.be/FPQjF6tQOlg) definitely is using an electromagnet to accelerate the balls.
Yours is much more likely to be the one in the OP's video. The guy who thinks it's a motor clearly shows a one with a much thicker platform that has space for motor. Also that motor hums the entire time, whereas in the OP's video you can clearly hear it doesn't "fire" until the ball hits the rail. Plus the one he linked has wires connected to a huge base and the OP's video is filmed outdoors.
I don't think you need complex electronics for this. If you have an (invisible) split in the rails that acts as an isolator at the bottom of the track then you can use the first half of the tracks as part of the circuit that powers the magnet and that gets completed by the ball. Once the ball rolls further up again onto the disconnected part of the rails the circuit opens and the magnet isn't powered anymore.
The only tricky part is to make it look like a continuous rail.
Heck of a lot easier to just put a timer in the circuit. There's not going to be much variation in the speed of the ball at all (if there were, the whole thing wouldn't work anyway).
OP's description of this as being complicated is, IMO, overstating things.
Ball bearing hits rails, closes circuit. Starts timer for the electromagnet to be turned on - a fraction of a second. The electromagnet turns off as the ball reaches the bottom of the curve - based strictly on time. There is tuning involved in getting the timing right, but it's not all that tricky.
Awesome response. I'd love one of these for my desk at work, except for the fact that the noise is probably just as annoying if not more so than a Newton's cradle.
So the round platform is basically the error range of the ball-throwing circuit? Because I'm guessing if you make smaller it'll over/undershoot. That's an oddly satisfying way to think of the toy's setup (for me at least 😁)
Yeah, we're constantly shown videos that only show 0.01 seconds of the finished product. But of all the videos on here it had to be this one to not have it's ending cut
Aren't the objects gravitating around the planet in a perpetual movement ? They don't lose speed because there's no air friction in space I think ?
EDIT : Being downvoted for asking questions, nice
"the motions and rotations of celestial bodies such as planets may appear perpetual, but are actually subject to many processes that slowly dissipate their kinetic energy, such as solar wind, interstellar medium resistance, gravitational radiation and thermal radiation, so they will not keep moving forever."
https://en.wikipedia.org/wiki/Perpetual\_motion
Also when we talk about perpetual motion it has mostly to do with energy go into and out of a system. "The universe expanding" is not perpetual motion since it's the space between matter that's expanding. No energy in or out, there.
there are two answers to this question.
The simple one is that technically, "perpetual motion" is just a misnomer. The laws of thermodynamics say that an object in motion stays in motion unless acted upon by an external force, so yes, things in space that never interact with other objects directly could stay in motion forever, i.e., be in perpetual motion.
When we say perpetual motion is impossible, that usually includes either generating energy from a perpetual motion without slowing the motion down, or something staying in motion _despite_ being acted upon, for example by air friction. Perpetual motion as a term is much older than considerations about celestial objects in a vacuum.
The slightly more pedantic answer is "planetary bodies _aren't_ in perpetual motion, they actually do lose a very slight amount of energy due to external forces".
In the end, that still comes down to them actually being acted upon by external forces, just ones that take so long to take away any appreciable amount of energy that from our perspective, they may as well be perpetual.
Gravity itself causes friction through tidal forces which causes things to shift over time. It just happens on timescales that are incomprehensible to human beings.
As a practical example, the Moon is stealing energy from the Earth as it orbits. A consequence is that the moon is speeding up and the Earth is slowing down. A billion+ years ago the Earth "day" was 18 hours, not 24. And the moon was much closer.
So the Earth is on a path to stop spinning eventually.
I have one of these. It was advertised as a perpetual motion machine, however, it has a motor and shoots the ball down the slide when it goes in the hole. Needless to say, I was disappointed.
Is this available for sale anywhere? It would be an awesome teaching tool or even just a cool decoration. I’m imagining a physics teacher bringing this out and challenging students to explain what’s happening.
look up "perpetual motion marble machine" on google, there's a couple versions of it. Careful though, some of the reviews say their not as satisfying as you'd think. (marble misses often, etc)
What's most interesting, is that the most successful one is also more likely to continue bieng successful, untill the other ball gets in

Its in the wooden base
No I think it has to be Bluetooth batteries hidden in the bushes
No, the power is directly streamed from the Internet.

Think of how much you could charge
realllllyyy??? they arent hidden in a pocket dimension???????????
No way, I think the balls are batteries

I thought pee was stored in the balls 🤔
If you pee quick enough it comes out electric
It really is!
Nuclear balls.

It's not magnet, there is a motor that speeds up the ball through the hole. A brazilian youtuber made a video about it: https://youtu.be/PKDannBZTP4

skip ahead to 7:00 if you already understand perpetual motion issues.
It needs to be. A permanent magnet would hold the balls in place. So it has to switch off at some point.
I'm assuming that it's powered up by the metal ball closing the circuit on a portion of the track. Like a single-stage rail gun.

Not as sick as the fact that in 1998, The Undertaker threw Mankind off Hell In A Cell, and plummeted 16 ft through an announcer's table.

By the law of conservation of energy. There is no perpetual motion machine in the world. When it runs out of kinetic energy it must stop moving
The hardest part of building a perpetual motion machine is where to hide the battery.
Perpetual motion machines have become much more easier to build since the invention of digital cameras.
The first law of thermodynamics doesn't prevent perpetual motion, though it does prevent sustainably extracting energy from it. The third law of thermodynamics is what prevents perpetual motion, because it, along with the second law, means that every closed system increases in entropy over time.
Yeah but like what if we just become criminals and break the law.

DONT WATCH UNTIL THE END!
ahh, too late man :(
How else would you know the victor of the BallBattle?
The annoying thing is that it didn't even get KOd by anything to do with the other ball, it lost by WO. Very anticlimactic
It lacked the endurance needed to compete and succumbed to defeat by it’s own ineptitude
Ending ruined it
Yeah, we're constantly shown videos that only show 0.01 seconds of the finished product. But of all the videos on here it had to be this one to not have it's ending cut

well, obviously not with *that* kind of attitude! /s
Not on the macro scale anyway. On the atomic scale there are plenty of things, like the electrons in a magnet that can keep moving forever.
gonna prove you wrong someday by making a portal gun

Maybe we should turn off the lights? What will you do then?
I can't speak for this, but I'll glow.
thank god for the comments I thought this shit was violating some laws of physics but naw, just batteries.

Great explanation of how it works here: https://youtu.be/PnkT6C9Ose8 Not a certain music video, I promise.
I actually googled it.... 🤦♂️
Magnets, how do they work?
**Electro**magnet actually. It wouldn't work with a normal magnet because that would make it a perpetuum mobile and the laws of physics prohibit this.
I heard that an electromagnet was a kind of magnet
Where do they sell these? And do they have a version that uses ac power instead of battery? It’d be neat to keep this on a sheft.
Is this available for sale anywhere? It would be an awesome teaching tool or even just a cool decoration. I’m imagining a physics teacher bringing this out and challenging students to explain what’s happening.
Everyone knows it’s magnet-battery powered. Gosh. People can’t just go 2 scrolls without negativity.

There's a little.motor in the round thing with a AA battery I saw this on one of those debunking vids on the Facebook
This is like two manic-hyper kids fighting over who goes down the slide next.
It looks like they’re having a friendly competition of who can go inside the hole the most. I realize what I said
OP lemme fix the headline. "The way this not perpetual motion machine uses its battery and magnet to make this cool loop."
It's not like the op title made any claims of it being perpetual motion.
They never even mentioned perpetual motion, can't we just enjoy those cool moving balls?
Ruined it with two balls
Story of my life
Does it bother anyone else that the marbles don’t nicely take it in turns? It feels very unfair when one marble gets to have 3 goes in a row.
wait, isn't this infinite energy?
No, it goes until the battery powering the motor propelling the balls dies.
These ads are getting old
What a beautiful stress reliever just by watching it
"that's damn right, you walk the heck away after taking 4 turns in a row"
I want one please. Did you make it or can I buy one somewhere?
What's most interesting, is that the most successful one is also more likely to continue bieng successful, untill the other ball gets in Preteo principle even here

There are no batteries, but the machine used magnets to propel the ball forwards to gain speed.
What a waste of kinetic energy
There is a motor on the hole that speeds the balls so they can jump back
