- Can glass be magnetic? Usually we would say no, but in this video I show that all glass react to a magnet in some way and some even react so strongly, that you could call them magnetic!

I like the sound when gadolinium glass was bouncing off the magnet.
Yep - rounded, not too strongly attracted objects can make that nice rattling sound. It is also utilized in 'rattlesnake eggs'. A magnetic toy designed to make that sound when thrown together in the air. Thanks for watching!
Yes, I agree. That sound has a very ASMR like quality to it. :)
3b1b vibes
This sound is truly peculiar and not just for the individual - there is even a souvenir called "Buzzing Magnets".
I have had this souvenir for a long time and occasionally enjoy listening to this sound - the speaker probably does not convey exactly the same sound as the magnets actually do.
These magnets are demonstrated here: ruclips.net/video/L55Lki8qqSc/видео.html
Love your informative videos, thank you
I thank you for this. I love that you include experimental data and discussion of boat drag with correction for weight of the beads.
How about testing a solution of a gadolinium salt in water?
Then precipitating pure gadolinium silicate and melting that into a glass bead?
@3:26 I just love that sound of the gadolinium glass bead bouncing off the magnet.
uranium glass is the coolest thing ever
It is amazing to me, that it doesn't cost more than it does. Cool to collect and will never be made again. I guess they produced tons and tons of it back then - keeping the prices low. Or maybe people don't like having radioactive things in their home anymore :o)
@@brainiac75 how dangerous is uranium glass? im guessing it would be a good idea not to eat food out of plates made out of this material.
@kvykimo indelis It is if course less safe than non-radioactive glassware. But it honestly isn't that radioactive. In my opinion it is one of the safest ways to collect radioactive items. I personally don't eat or drink from it, because I have a non-radioactive kitchen. I follow the ALARP principle :)
@@brainiac75 I have a few box's of u glass
I was gonna say it does look really cool despite being a little radioactive lol
Super interesting as always! Who would've guessed that so much go into a single glass bead?
ceramic engeneering is ,,,super complicated. glass is a really complex structure, it has 2 regions. a silica rich area..and a flux rich area. and you can fit all kinds of elements into it in a zillion different ways. ie..all the new metals in cars are actually glass now. they are super cooled liquids ..memory metals. same formulas..different production methods.
@@autopartsmonkey7992 wow, i never knew that! Glass is so fricking cool!
Thank you for sharing this. It is something that we simply take for granted.
The little checkered flag was a very nice touch by the way:)🇬🇷☮️
Who on earth can down vote this delightful scientific presentation!
Somebody expecting DC Comics content?
only four people. And I those are just jealous bastards
Your content is always exceptionally intriguing! Oh and your video editing skills are fantastic too!
Thanks for the quality vid before I lay down for bed, Brainiac! You truly are the highlight of my weekend!
Also, thank you for the bloopers at the end. Love your stuff!
This was a very nice video, I’m always happy when you break out the Uranium glass. I’m also happy to see that, each video, it seems like you gain more and more patrons. Your work has taught me a lot, and I’m sure has educated many others. I just wanted to give you a heartfelt thank you, Brian. Keep up the wonderful work!
I like the glowing in the uv lights glass
7:30 The supplier wrote that "Other substances are added to the beads for moisture-resistance". That sounds crazy. I cannot imagine how glass would not be moisture-resistant. Perhaps it means that if those other substances were missing, the glass would become a little dull and less shiny after contact with water or moisture. Thank you, this is great work and very well presented.
I just want to say that All of your videos are very entertaining and very informative, You do a great job Keep up the great work.
This guy sounds like a guy that would commentate Planet Earth
for real xD
I could totally see his voice fitting perfectly in Adventure Time. Correction, 'hear' his voice.
Nice. I would love to commentate anything BBC Nature (Natural History?) makes. Their production quality is through the roof! Thanks for watching!
@@brainiac75 hi, where did you found those glass bead ?
@@crazynfc2667 6:46 ? ...just a guess
Amazing as always. Love uranium glass. Sometimes it's cobalt blue in color.
More than a THOUSAND 👍
And only three👎
What a ratio!
Everything is magnetic, if you have a magnetar close by. But I don't recommend trying that at home. Go to a friend's house instead.
Aight I need uranium glass now
I learnt more here than in a day at school
He is the replacement for all the physics teachers :p
I learned more on this channel than four years of high school
Please do not learn anything while at school (daycare), you will regret it later as an adult.
@@agvulpine bruh what do u mean?
@@jeonneonnyan6074 the first thing you are taught in college or on the job is how to unlearn everything you learned in school.
I just woke up and, strangely, I was asking myself if glass can be magnetic. I absolutely love this.
Besides being an interesting demonstration, I really liked your choice of music with the video. Good one! :oD
So excited when ur videos come out think because there like 1 or 2 a month it makes me want to watch them more
i love the music during the boat races...made it so engaging lol
Very clever setup with the pneumatic actuator
these would be a interesting lab at a science class in a school.
I really enjoyed this video, thank you.
What a great video. Just amazing.
Damn you're own a roll with the video output!
Well, I have been publishing a video every month for almost two years in a row now. As long as people have interest in my videos, I will keep making them. Thanks for watching and commenting!
Nice LEGO contraptions for testing!
I wonder if the styrofoam was repelled by static electricity rather than it's magnetic properties.
2:19
@@DirtyLew42 Maybe electrical than magnetic.... that is the part I am referring to.
Paul Trigg it wouldn’t effect the test tho
@ Paul Trigg I doubt it. The styrofoam is sitting on water, and water is good at discharging static electricity. Try making anything static electric in moist air or in contact with water ;) Thanks for watching!
I would wager to suggest that static electricity and magnetic properties are one and the same thing.
I will not click like because I don't dislike what you do. I will click like because I love what you do.
That's even better, thanks :D
I wonder if suspending nano particles of metal in glass (or another medium that holds its rigidity), would increase (or decrease) a given magnetic effect vs that of the pure metal constituent.
I posit that the surprising magnetic effects you are seeing with metals in glass are due to this effect.
It would be interesting to test this theory or (find papers that have already experimented with these properties).
Fun stuff! That took a lot of work. Thank you.
Thanks! It did take a lot of patience to make this video. Both for the tests and the editing. HitFilm's timecode function is not made for this kind of use....
I really like seeing the 3 Electrical conductor metals, Copper, Silver and Gold being so strongly diamagnetic.
this channel is so fucking sick! how is it not popular af!?!?
10:08 hmm, yes, the floor here is made of floor
Well done, interesting video.
I used to have a number of uranated glass marbles; it was always a kick in the pants when I irradiated them with visible, NUV, or UVA radiation and watched them fluoresce! :-)
Gemstones also paramagnetic or diamagnetic response, and some jump to magnet like ferro:) Thank you for magnetic series very much!
I definitely want to get some Uranium glass. Great video. Shout out from rural Maine, USA.
Why am I just now learning about magnetic glass 🤔
It was interesting cheers for the info
YEAY! ANOTHER VIDEO! 😁
love the color of the Holmium bead
Man, do i like these magnet videos.. 👍
Very cool!
Hey Brainiac75, love your stuff! Where did you get your glass samples from?
Loved the " Niiiiice " at the end. I would have cussed. I am trying to change, really... : ) Very interesting video !
Hehe, I'm not saying nice in a sarcastic way. Try turning on English subtitles. I'm actually saying no in Danish (Nej). It was quite a work to get all those tests done. Challenging, even for my patience... Thanks for watching!
Love the Lego checkered flag and use of Lego.
Uranium glass is good stuff. Gonna need to get my hands on some of that. I suspect ebay searches for it could potentially lead to an increase in prices.
I did like the fact that some glass beads were repelled and some attracted (the cerium and gadolinium were great) but this could be down to polar orientation of the bead and if it was flipped over, it would do the opposite of it's previous reaction but it's and interesting effect making me wonder about the material alone, never mind the glass.
Great video and keep up the good work.
Awe struck, again. Thanks Brainiac75!
I'd be curious to see if the gadolinium bead results would vary depending on temperature. Test it at multiple temperature points, say -20°C, 0°C, +20°C and +100°C.
How would you keep its temperature at those levels while performing the experiment, though?
Excellent question. I would assume you would just have to be VERY fast but I may be wrong. I'm just the idea guy. :)
@@Enjoymentboy Well even if the test lasts only 10s, that's plenty of time for the bead to cool down quite a few degrees if it was at 100°C and the air was at ~30.
You'd have to use some kind of device that maintains its temperature throughout the experiment, or design another experiment altogether.
@@ZeroZ30o for -20 he cud use something like liquid nitrogen like substances which drop to only -20 C
@@ZeroZ30o maybe airtight setup filled with hot air?
I love magnet videos! I will make spanish subtitles 🐱
Thank you very much. That would be awesome!
Some steady hands you got xd 9:57
what is it with lanthanides and strong magnetism?
Amazing!
Does the metal being held in place by particles of glass create magnetism in the same way as neodymium does with iron in neodymium magnets?
Gadolinium has something like seven unpaired electrons in its F-shell. That's why it's used as a contrast agent in MRI imaging. There's a difference between bulk magnetic properties and 'microscopic' magnetic properties.
What are the differences between the metals used against light or UV rays and are there any that block flashing like in welding
What would happen if you spinned the giant neodymium magnet on a coil? With such a strong magnetic field im expecting a high enough voltage to power some stuff
I'm jealous of your collection of glowing glasses
You could test the effects of weight with iron fillings. The material would be homogeneous enough for your purpose and the weight of each test would be easy to control.
Nice video :)
Where are some practical examples of Gadolinium glass available in products and retail? Both for purchase today and purchase yesteryear?
need to rig up a force meter with thread/string a solid distance outside the magnetic field. You could suspend the beads, zero the scale, and slide magnet under. Would remove the boat and drag entirely.
I also collect uranum/ vaseline glass. Looks awesome under black uv light
Good video!!!!!
Was there any information given about the % concentrations of the doping metals in the glass? After watching the first two tests I can’t help but think the unexpected top performers may be due to a higher metal concentration than the rest. Perhaps this could explain their more pronounced response to the applied magnetic fields.
If all the beads were made by the same company, one would think they should be pretty much right on point for % concentration. However without that info it definitely is a confounding factor in the initial tests (haven’t yet finished the video).
Edit:
You showed a few labels, but only the holmium and erbium beads had a molar % listed (5%). I didn’t see anything on the other two.
As mentioned late in the video, I did not get much info from the seller (which is also the manufacturer) about the exact content. I do suspect, that the gadolinium bead has a higher concentration. But again, this is not meant as a test of the elements magnetic properties. It is a test of the glass beads with their different metal dopants. Thanks for watching!
Where do you get these glass crystals from can I buy them off anywhere?
I bought them from smart-elements . com I have bought a lot of my element samples from them as well. But they are not sponsoring my channel - yet... Thanks for watching!
A video on magnetic flux permittivity would be interesting, maybe even magnetic saturation, for example I've heard super permittive metals can have a low saturation point and act diamagnetic. They can also be used in magnetic shielding.
I never thought that glass doped with a paramagnetic element could be more attracted to a magnet than iron doped glass...
Out of curiosity, did you notice any color changes while in the presence of the magnets? or is it only the light sources that changed the color?
I still love your little black & white finish flag!!
It's a LEGO flag. Being a Dane, I have quite a collection of LEGO from my youth (Danish company). Why not use it as an adult too x) Thanks for watching!
You should really make a Gouy balance to solve these problems. You have the capabilities and resources and it would be a great addon to your precision devices.
Where did you get the glass?
Can you test if they react to light any differently while in a magnetic field?
Hi. I like the video very much. And I have to state that I do not use Gadolinium in any other glasses than in the Gd glass itself and the Cerium glass.
Cool video. Why not go with time per mg?
Also what did you do to compensate for any static charge of the boat and your body or the timer release arm?
Thanks! There's not a linear relation between time and weight, so time per mg won't work (ruclips.net/video/wf69Evtsa_Y/видео.html). Water is very good at discharging static electricity. Have you tried making something static electric in direct contact with water or just in moist air? It's almost impossible :) Thanks for watching!
I think these glass beads are so cool.
I appreciate how you refer to tungsten as Wolfram, it's a much more fitting name
Tungsten (literally heavy stone) is the original name of the ore, not the metal.
Calling the metal tungsten is a bit like insisting all iron should be called magnetite.
@@0LoneTech knew someone who was more into minerals would find my comment eventually if it needed to be cleared up, and thanks for doing it
#Braniac75 someday you should test the magnet proprties if different noble gases such as hydrogen ice cube, oxygen, nitrogen, helium balloon, neon, argon, xenon, and krypton bulbs! I love your channel!
1:06
Brainiac: Now the uranium ions fluorescents with a deep green color.
Me: uh- hate to break the glass but that's bright green
I have a smaller but pretty strong and my neighbor and her younger son were visiting and when I let her son play with the magnet and he was sticking it to different things when he walked to my sliding glass door and he lifted his arm and stuck it to the glass put his arm down and lifted it back up and grabbed it from the window I asked his mom did you just and before I could finish she said yep so I grabbed the magnet and checked to see if it had stickiness and it did not I tryd putting it in the same spot but it wouldn’t stick again do you have any explanation I can’t understand how
I was expecting the Gd bead to go flying onto the magnet and shatter in the "race" test.
very cool
I seem to remember a video of a frog being affected by a magnetic field. Which would lead me to believe that anything can be affected. Then again maybe it was just the iron in it's body.
Fascinating.
I tried to fall asleep, and when on the verge, the question, "can clear glass have magnetic properties", formed in my head, and that was it, 4:30 am and I was now up.
Are there any external influences that can be applied to increase the attractive force of the glass beads, such as temperature, electric current, or other?
for the races you should do multiple runs to measure standard error
Why this experiment was done by on not pure samples - all are mixes of diamagnetic glass with metals para, ferro and diamagnetic. For me it would be more important of measuring their magnetic force per weight of pure sample. That time we would get some information which metals have the strongest and weakest properties in respect to interaction with magnetic field.
Maybe do the same test but see what glass beads repells the fastest
Awesome video! Loved every bit of it.
mattw shut up time traveler
It maybe possible the magnetic property is in the process of producing the glass bead, not just the metal properties in the beads. All these metals are produced, and the way they are produced can have an effect on behavior.
-What next, a glass magnet?-
Glass transformer
I love the lego Technics kit! Proper stuff and was that a Geomag piece I saw at 7.10?
Well, I do have a lot of LEGO from my youth. Why not put it to use as an adult too :D Yes, it is an old-style Geomag. I also used one on the sphere magnet to indicate where the strong poles are on it. Impossible to see otherwise. Thanks for watching!
@@brainiac75 I have a Geomag 96 colour it's the best toy I've ever owned, I'm 38. Hehe
I'm not so sure about that iron glass sample. In pig iron smelting, the casting sand turns emerald green from the iron contamination. Iron is also the reason Alsatian wine glasses have green stems. I believe your sample must be some other metal or an iron oxide rather than elemental iron.
After seeing the tests, I believe it is Iron II oxide.
Iron show up in very different colors in glasses. In phosphate glass and also borate glass it always looks brown. Depends on the oxidation state. I lime glass it is green as you say.
Which magnetic glass would be a good alternative to steel core of transformer? Also which glass would be good for making a capacitor?
In both cases, none of them. The magnetic permeability is still way too little to be useful as a core, and none of these glasses will be a conductor, which is what you need for a capacitor.
@@AlphasysNl By capacitor i meant using glass as a dielectric material between two metal conductors to store energy.
I always thought The Simpsons were exaggerating the green glow, but maybe Springfield nuclear uses UV lights at their plant lol.
Thankyou.. Can you do a video the electricity and magnets,
Magnetic games is the only one who has done a brief video on it,
I would love to see a dreamcatcher made of lightning..
If you put them in NO2 do they change their properties?
Cooling stuff to cryogenic temperatures will often change the magnetic properties. I have no idea what magnetic effect it would have on these glass beads though. Thanks for watching!
