For a while you've been making videos that are honestly some of my favorite on the entirity of youtube! They're niche but interesting and engaging which I find so impressive. They're also sneakily educational which is wonderful. Thank you for the incredible works.

As a kid I once accidentally found two oddly-shaped magnetic rocks while goofing around in my neighbors’ backyard, and I loved them, and they made a similar sound. Sadly I’ve since lost them but I have never forgotten them.
That's also how magnetism was first discovered way back when :) they would've been called lodestones for the longest time. Some cultures highly valued polished and shaped ones, I wouldn't be surprised if they liked the sound too.
@@kaitlyn__Lwould a naturally occurring lodestone have a strong enough field for something like this? I think of lodestones, that they have enough of a magnetic property that they will attract each other, but not enough to really do the same as this. Additionally the lodestones would need to resist any plastic deformation and restore back to their original shape after collision, so I'm not sure a natural rock would have that property either.
@@R.B. most weren’t strong or rigid enough, but that’s why ones as good as this were so highly valued. I’m sure it’s a super small percentage compared to what we crank out, and likely not as loud.

They were put into necklaces, brackets, and stuff; I remember seeing a few bracelets in a display (in the Ashmolean Museum if I recall correctly).
Great video! Fun fact, the magnets don't bounce infinitely many times due to the air's viscosity... There is a cutoff for a critical Stokes number (and another characteristic elastic number) for which particles approach one another without rebounding.
@@TeamTechSkatersheat is just the magnets buzzing at a very small scale, so technically, yes, in the classical limit. But also no, heat/sound is actually quantized in solid-state physics, and also, with no air they wouldn't be making noise at all.
@@NXTangl I had replied but I need to investigate your comment about solid-state quantization before I think I make it again. Care to explain so I understand? What I had said before is that heat will still be generated by the exchange of kinetic energy even on the small scale. This exchange excites the atoms and would give rise to temperatures because heat is still incurred, even in a vacuum. To answer woomy's question in an applicable sense, no system is closed, and losses are always expected. If start changing givens, my answer may change
My greatest accomplishment in life will be when I can understand everything being said in physics videos like these. I understood about half of the video so I’m getting closer.
Stuff like this is why so many physicists are also musicians! Understanding harmonics comes far more naturally after you've played with timbres and disharmonic overtones in a musical context. (Which is exactly why I suspect the creator chose this subject!)
Something about this video hit different. They usually feel like you are here to teach me something neat, but this time we were on an adventure to calculate the physics of a random part of life! It was so much more engaging!
8:39 it shows vertical lines because the bounces produce pulses, those are clicks that contain a wide band of frequencies. While the pulses repeat at a rate below haas they're perceived as separate clicks and not as a tone, that's why humans don't hear tones below 20hz, we instead perceive it as discrete rapid hits, and the window of the spectrogram is usuallt configured accordingly. Once the frequency of the pulses goes above 20 Hz they enter the window size and the signal can be plotted as a pulse wave of that frequency, with its fundamental and harmonics, just as we can start hearing it as a pitch. It's very interesting!
I absolutely love your videos because they're this wonderful combination of niche topics with eloquent explanations and amazing visualizations! Nothing else on RUclips can come close to these! Thank you!
As an engineering student my first thought after realizing that the force is inversly proportional to the inverse of the distance, was "Just approximate with a linear function", so when you said you're gonna assume constant force it just got better.
As many said, your videos are amazing. One thing I have to mention is about your video on music. The part where you explained why and how certain harmonies sound good for us has a special meaning to me. I experienced this before watching your video, while messing around with sound. Your explanation was kind of a miracle to me.
I used to have a pair of those magnets as a kid that i haven't thought about in almost 2 decades. Amazing video as always, and thanks for the blast of nostalgia!
Just discovered your channel: love it. You elaborate with simple but clever and effectice animations, and you explain the math behind it without dumbing stuff down too much but pacing it enough that its entertaining even to people who aren't here the check or recreate your work.
I'm an Audio Engineer, and I just found a couple of these magnet sets the other day! I'm absolutely going to try to get a higher resolution spectrogram.
It wouldn't be perfect. Every material has it's own resonant frequencies which would help sustain some frequencies while muting other frequencies. This is why different shaped rattlesnake eggs sound different. Making real world sounds synthetically is really hard.
this is one of the first things i ever modeled when i was first learning programming. i modeled the finite bounces by simply having a threshold for velocity where if the velocity of a ball was below the threshold, the velocity of the ball in the y direction was set to zero, and a different threshold for the x direction. this allowed for separate coefficient of friction and restitution and resulted in super realistic bounces. you can model this very easily though without using any formulas and instead just adding values each frame of a simulation with discrete time. if you make the discrete time steps 25 ms or less, your eye will not be able to see the steps and it will appear continuous. its pretty slick
I really enjoy your videos. I feel like all of them are stuff you fell into a rabbit hole googling then realized you had enough understanding to look into it much further than the average person
it would be really interesting to use the equation to synthesize audio waveforms and see how well it matches, plus turn some knobs to generate sounds from preposterous magnets

I think he integrated the force over distance to get the work done and equated that to KE. However there is a much simpler way to arrive at that result. F = ma so a = F/m v = at so t = v/a = mv/F But this is the time taken on half of the motion (ex: to stop) so multiplying by 2 gives 2mv/F
Dude I watched this high has a kite and while I didn’t understand the math at all; I was thoroughly intrigued and impressed by the quality of this video, well done homie keep doing this!
Hi I just wanted to say thank you. Recently I went on a trip to Georgia to visit a museum and I bought those magnets. I loved playing with them until I dropped them on the tile in my house and they cracked. When I saw this video it made me so happy
As with all of your videos, this is really good. I have a serious question - have you considered writing some of your projects more elaborately, using error measurements and the usual structure of a paper - and publishing it by yourself?
I'm not a physics guy, but this video was awesome. I liked seeing calculus used! I don't really intend to study and use many physics concepts, but I really respect people like you who can find a question about something and just use them to find the answer.
I was curious what the actual coefficient of restitution those magnets have, to see if your estimation was accurate. To my surprise, not only could I not find restitution coefficient for hematite (what these magnets are typically made of), but I couldn't find it for almost any material. There's only a handful of charts on google that show CoR for common materials, but there's no real go-to repo to find those values. Might be a good/helpful project for someone to work on. Great video by the way!
That's because CoR isn't a property of a material, it's a property of a pair of objects. Think of steel: if you drop a ball bearing on a big steel plate, it's gonna bounce a lot. If you drop another steel plate on top of the steel plate, it isn't.
One of my Professors once said "that a good theoretical physicist knows what approximations to make, before he knows if he is even allowed to make them." Very nice video highlighting what you can predict even with very simple models.
I opened the video thinking it would be someone clanking the magnets for 10 minutes. Ended up watching the whole video and got a mini lesson to boot, I call that a win.
I really enjoyed this video! The explanations are straightforward and I really like your use of coding tools for analysis. It really gives the video a “hands-on” sort of feel!

If I was a spherical human in a perfect vacuum, this is the kind of stuff I'd spend my time on all day.
If people knew how easy finite element analysis was with ms excel, they could remove all the silly assumptions

not if. When.
Don't forget that it's a perfect yet breathable vacuum.
Did you just point out being spherical because otherwise you would have spent all your time wanking?

I hate how I don't understand when you start speaking math, and then brain just go back to "heehoo, magnet make noise 🙃"

It would be interesting to use those frequency curves to synthesize an audio clip, and see if it sounds like the real magnets.
It wouldn't be perfect. Every material has it's own resonant frequencies which would help sustain some frequencies while muting other frequencies. This is why different shaped rattlesnake eggs sound different. Making real world sounds synthetically is really hard.
Came here to say this. You would have to model the vibration response of a single magnet when struck and layer that over the bouncing response.
"Just shy of infinity" is my new favourite phrase
I think you will get clearer results if you use the sound from 0:48 instead.
It’s really nice to see a science channel that doesn’t explain how sound waves work like there talking to pre schoolers
I remember how much I used to play with these as a kid. Never knew there'd be a video so many years later explaining how they work
I love that the example music at 8:15 is the infamous "the lick".
