- Опубликовано: 7 янв 2012
- I believe this video is unique. I haven't found a video on RUclips showing so many different metals and their effect with magnets. I dream of getting all the available elemental metals and make updates for this video series.
I have had quite a lot feedback suggesting that I should have put the magnet on a string or scale so smaller effects would be visualized. I use this in newer parts of this series:
Part 2: • Exotic Elements vs. Ma...
Part 3: • Exotic Elements vs. Ma...
Part 4: • Exotic Elements vs. Ma...
Part 5: • Exotic Elements vs. Ma...
Part 6: • Exotic Elements vs. Ma...
I may at some point redo this video with more sensitive setups, but with 41 metals it is quite a large project :|

This guy have all the elements at home 0_o
But I have the Element of Surprise!
Am I sensing an element of sarcasm? Videos like these should not contain elements of mockery! This information is elementary to our understanding of the elements of science that we learned in elementary school in a very elementary way. We must be serious when discussing all the different elements of scientific discovery, because there will always be an element of mystery that requires an element of maturity to decipher.
He owns the periodic table
Polonium is most dangerous element so he cant keep it..
THIS VIDEO IS THE MOST METAL VIDEO ON RUclips!!!!
Ok, that got a chuckle.
This has to the most jolly part of youtube. ^^ Haha relaxing music, insightful comments, actual politeness. Wait, I'm on youtube?
I believe music is borrowed from K-Pax movie. The piano theme is remind me of that movie.
The force is strong with this one.
trppmdm I know right, it's hard to believe
if believe youtube now was as good as it was 7 years ago...
@@RUclipsrBack Hey man, check out NileRed! Definitely a similar vibe and community!
You should remake this video, but this time hang the magnet on a non magnetic wire like a pendulum so we can see the very effect of the very low effect ones and notice the difference between the metals.
+Haikiri Nanbo good point
+Haikiri Nanbo He does this in part 2. Dude listens to his audience.
Yea, this video is rather pointless. Nothing to see.

Hi, I can't reply directly to your comment (have you disabled replies?). Hope you see this.
The hazard label of cadmium was a European standard that shows that cadmium is an environmental hazard (dead tree and fish). The symbol is now updated to a global standard (en.wikipedia.org/wiki/GHS_hazard_pictograms).
Thanks for watching and commenting!
how do you get all these elements 0.O
Can you provide a link to where you got those rare earth metals.
Isak Mohamed I bought the set through eBay, but the seller has his own website: www.smart-elements.com/?arg=detail&element=Set&newitems=&limit=1&art=00174&pn=&cat=&view=gl&tr=10&out=1&lid=15&PHPSESSID=a7d2ffd37834b8aaddb26735b7291fad#A
Freeze the mercury with liquid nitrogen, then pull out the glass.
Enrique Suarez Uranium is found in many minerals, but Plutonium is really not, although most elements can be found naturally on Earth, but not in pure form.
7:35 I approve of the use of legos. I too have found some random practical purposes for them.
Thank you :)
I am providing the energy in the setup. I am holding a 'lifter' magnet above the two discs of bismuth and by moving the lifter magnet up and down I can control the small magnet between the bismuth discs. If I made a rig that could hold the lifter magnet completely steady I could make a more stable levitation (balancing several forces: gravity, magnetic fields and diamagnetic repulsion).
Thanks for watching!
You can find most on eBay (like myworld.ebay.co.uk/onyxmetall/) or in dedicated webshops like smart-elements'com. I don't know much about the American market but there are without doubt also some in the US.
Part 3 to this series will come in August - subscribe to get reminded ;)
Imagine if he drooled on that lithium, quite the bang i'd say
Very impressive collection. I'm going to have to buy some bismuth now. Thanks for sharing.
This is my hobby and filmed at home. eBay is my friend when I need to find the rarer stuff ;)
It's one of my favorite metals too! It is used in the world's most powerful permanent magnets, in the lovely green lasers and it's compounds often have some interesting color-changing effects. I'm planning to show this in an upcoming video with neodymium chloride and neodymium fluoride.
Even Periodic Table of Videos don't have this much metal samples.
You should have hung that magnet to a very very long string so that we can better see the effect (Paramagnetic / diamagnetic etc)
+Vikram Pandya
Yep, this video was the first in the series. Part 2-4 are much better due to feedback from my viewers (links in the description box). So I may have to revisit these metals in a future video. Especially the rare earth metals which are quite paramagnetic.
Thanks for watching and commenting!
Thanks for your response, I already subscribed due to interesting content. Keep up the good work :)
+brainiac75 Hey, you think you could re-do this video with the new methods (Water, magnet on a string, etc...) so we can have a better idea of these metals properties?
Miguel Peralta Yes, that will likely happen in the future. Right now I just have so many video ideas in my head that will be more interesting to make.
But I definitely have to re-visit the set with rare earth metals vs. magnet. Most of them should have a very noticeable reaction in a sensitive setup - despite the glass ampoule and small sample size.
+brainiac75 Yeeeesss!!! I've been waiting for that ever since I first saw this video. Thank you!
Love that this is still available. Quality content from a much younger RUclips. Very nice to see the difference in your editing and stuff as well. Great work!
Not really forgotten - more an issue of money ;)
In part two for this video - Exotic Elements vs. Magnet - I promise a gold sample for part three since gold is the most requested. Getting a visible sample of gold is just so expensive that I prioritized to get as many metal samples for the first part instead of just a few expensive ones.
Thanks for watching!
Dat relaxing music.
Thanks for the video!
What a GREAT VIDEO!!! Thanks so much for your work, you are a gentleman. Lol. And I agree with the other comments, THIS here is what RUclips is about
This was one of the first videos I ever watched on RUclips, and it brings back so many memories
Them slow movements hovering the metals over the magnet are unintentional ASMR triggers
Is it possible to mix every (or nearly every) element together? If so what would happen?
That's how they make Monsanto Roundup! ;)
GreatOxInTheSky. That's very funny, good job!
Yourname942 it would probably be a highly explosive device
That tungsten cylinder sounded like a brick!!! 0__o
Gosh, I get all excited getting a look at all these different metal-elements!
Good thing that you know about conservation of energy!
I am providing the energy in the setup. I am holding a 'lifter' magnet about the two discs of bismuth and by moving the lifter magnet up and down I can control the small magnet between the bismuth discs. If I made a rig that could hold the lifter magnet steady I could make a more stable levitation (balancing several forces: gravity, magnetic fields and diamagnetic repulsion).
Thanks for watching!
What's the cost of uranium and where did you buy that
People online sell it
Cheap. Ebay. Duh!
I really wish he was my science teach
No, you need a superconductor cooled to superconduction to shield like that.
At normal temperatures you need something magnetic with high magnetic permeability to 'shield' (actually redirect) magnetic fields. Search mu-metal which is an alloy commonly used for magnetic shielding.
Thanks for watching!
Congratulations. You make RUclips worth while. Great job.
I didn't even know diamagnetism was a thing
You're not the only one :) For some reason we are only really tought about the ferromagnetism in school. The other forms of magnetism are 'forgotten'.
@@brainiac75 what do diamagnets do when dropped down a copper pipe?
Oh no Au5 in here 😃😃
a guy on youtube channel taofledermaus does a bunch of videos on mecury and he cleans his mecury with a sponge but he has 5 pounds of mercury... you would need a small sponge.
Thank you very much!
I hope to upload part 3 within the next month. Very-hard-to-find samples in part 3 ;)
Yes, it should be if you have a sufficiently large lifter magnet above the setup (and some seriously big slabs af bismuth). I doubt it would be spectacular though. It would still only be a few millimeters of levitation and therefore hardly visible with such a large magnet. It's better to use small magnets and pyrolytic carbon in stead af bismuth.
Thanks for watching and commenting!
here because of part 5/5
Nice :) This video is starting to feel old compared to my never videos but it still shows 41 elements in pure form.
The music :'(
tHE cOMUNIST pIZZA I like it too, but It makes me sad
i wonder what music it is
yes jeff
In part two (Exotic Elements vs. Magnet) I use much more sensitive setups. When I have time I will redo some of the tests in this video - especially for the rare earth metals.
It's from eBay. There's a similar cylinder for sale right now for $240 (search 'tungsten cylinder 1 kg'). 7 out of 10 are already sold so it is quite a popular item despite the high price :)
Thanks for watching!
so basically u wanted to show us ur variety of elements..?
Obviously because every element didn't do anything
Literally the most boring video ever😂😂
Daniel Yorke id interstibg he know all metals of the planet
GreenFlu TheWicked Did i miss something or is he really a show off, i mean gas pistol, ammunition etc. wtf.
He has ammunition and stuff to show real world applications for that metal...
Wow, thanks for taking the time to collect and set up every sample testing shot
Gold is coming in part 3 here in August. Meanwhile you can watch part 2: Exotic Elements vs. Magnet :)
Yep. The old term rare earth metals is quite misleading because many of them are as 'rare' as cupper, nickel lead and tin in the Earth's crust.
However they are rarely seen in pure metal form by most people because they are expensive to separate from each other and most of them will corrode very easily in the air.
Thanks for watching!
They don't ship to Denmark and their pure uranium has been sold out for a very long time. They only have uranium ore for sale (mineral samples containing uranium).
The sample in this video is pure uranium metal. If you want to see some of my stronger radioactive samples watch the video 'Radioactivity | My collection so far'.
Thanks for watching!
It's been collected over many years so I kinda lost track of cost :/
But all the elements in part 1-3 in this series I wouldn't sell for less than $2500-3000 (not really for sale - some of them are hard to find).
Thanks for watching!
Fascinating. Pure information dissemination. I very much appreciate this demonstration.
Amazingly nice set of samples. A very classy science setup...great video!
Thanks :)
I do plan to make an updated video with especially the rare earth metals and what they are used for. Telling in detail about all 41 metals would make a long video ;)
Thank you. Part two is even better (Exotic Elements vs. Magnet). Part three is coming very soon and will top them all in my opinion ;)
It's moving because I hold a 'lifter' magnet above the setup. If I made a rig for the lifter magnet and balanced it perfectly it could levitate for hundreds of years (until the magnet loses it magnetism - partly because of background radiation).
Thanks for watching!
I do have some smoke detector americium discs (watch my video 'Radioactivity | My collection so far').
The problem is that it's not the pure element/metal. It is americium dioxide lodged in a disc of another metal (often made of gold actually) so it will not show the magnetic property of pure americium.
With that said it is fantastic that we have a man-made element in our homes in a detectable amount (and it is the decay product of plutonium-241!).
Thanks for watching!
wow that's alot of effort put into the backgrounds for each metal! awesome!
Glad you liked it! Remember to watch part two 'Exotic Elements vs. Magnet' for more elements in an improved presentation ;)
Links in the description and in the end of the video.
Thanks for noticing! One of the challenges with this video was how to show 41 elements in an interesting way without being to repetitive. The different backgrounds made this a huge (and expensive) project but I think it was worth it :)
Thanks for watching!
The rare earth metals are rarely seen in pure form and their attraction to a magnet surprises many. I'll revisit them in an upcoming video with more sensitive setups and even include all of their oxides that may also react with a magnet ;)
Wonderful video, the bismuth floating was especially nice, graceful. Thank you for making this, superb.
Thank you for all your effort and hard work.
awesome video brainiac, keep up the good work
Among the music and his voice it's pretty relaxing to watch at it, I'll watch it before to sleep.

You're right: scandium + yttrium + lanthanides = rare earth metals. Should have clarified this in the video. I'll make it more clear in my upcoming video where I retest all rare earth metals in more sensitive setups including their oxides.
Thanks for watching!
Then you should watch part 2: Exotic Elements vs. Magnet!
Thanks for the suggestion. I have so far cleaned it somewhat with the simplest method: double-sided tape. It's not optimal but was quick and easy :)
I have actually bought a new mercury sample from a source without broken glass (sphygmomanometers) ;)
Thanks for watching and commenting!
The bismuth levitation thing was really cool! Finally YT has suggested some really interesting matter to me. Subscribed.
No, magnetism is an effect between electrons. Radioactivity is from the nucleus (protons+neutrons) so no real linkage.
Thanks for watching!
It's the number of protons that determines an element from another. Electrons can vary for an element (called ions, but still the same element). The number of neutrons can also vary for an element (called isotopes, but still the same element).
Thanks for watching!
Exactly! Unpaired electrons gives a net charge that causes ferro- or paramagnetic effects. Paired electrons gives diamagnetic effects.
Thank you very much. I'm currently buying stuff for part 1½ in this video series where I show all the rare earth metals and their beautiful oxides in a more sensitive setup. While you wait you could watch part 2: Exotic Elements vs. magnet :)
You may have experienced eddy currents (reaction with highly conducting metal and movement) which can be confused with paramagnetism (reaction even when metal and magnet is not moved). More about this phenomenon is in my video 'Eddy currents ad libitum'.
Thanks for watching!
You have no idea how envious I am of that collection.
Not all elements are possible to get in visible amounts - even in a laboratory. But collecting the available elements still takes some dedication and cash. If you can live with tiny samples and not to high purity I think a couple of thousands dollars + shipping could get you all available elements. I have just started collecting the precious metals. Their price tags are painfully high :(
Thanks for watching - more to come when I can afford it ;)
I found myself most fascinated by actually seeing most of these metals for the first time.
Coming in part three that I will release late in August. You can watch part two in the mean time: Exotic Elements vs. Magnet :)
wow i've watched this video so many times but never get bored :)
I cant believe you have ALL those samples! wow!
+kowalityjesus
It does take some dedication to collect so many elements in high purity - mostly because of the cost. Most elements are actually quite easy to find online. I hope to pass 70 elements before this video series is done - 65 shown so far :)
Thanks for watching.
The 'neodymium' magnets are actually made of a crystalline material of roughly 14 parts iron, 2 parts neodymium and 1 part boron.
It is a special, symmetrical arrangement of the elements in the crystal that give this material such powerful magnetic properties that no pure element has.
Thank you for your story about mercury! In the good ol'days mercury really wasn't taken as seriously as today where each new study seems to suggest that ANY exposure to mercury is really bad. A little dramatic as your story proves ;)
Pure elemental mercury is not madly poisonous (the fumes are dangerous in long term exposure though). It's the organic mercury compounds that builds up in nature that's the real problem.
Thanks for watching!
You are exactly right! Most of the helium in a party balloon actually used to be part of uranium or thorium in the underground that decayed with an alpha particle. The alpha particle then grabbed electrons from its environment and became a helium atom. Quite fantastic - I love science :)
Good compilation and analysis
More sensitive setups in part 2 Exotic Elements vs. Magnet. I may redo this video. It's however quite a task and you may be disappointed of how little reaction there is even in a string setup. But at least I show the elements :)
Yes! As soon as I get more pure samples (including gold) I will make part three.
Search the channel 'periodicvideos' videos about the elements to hear how the different elements are pronounced by chemistry professors - that's how I learned... :)
The magnet is a neodymium magnet made of iron, neodymium and boron (~Nd2Fe14B). The strongest permanent magnet material we know of.
Yes, alloying and combining elements can change the results completely. Magnetism is all about the electrons and their behaviour can be very different in pure elements and alloys/compounds with the element.
That's why I try to find very pure element samples for this video series. In part 2 and 3 I have samples that are not pure enough to behave in the right way...
Palladium is attracted to a magnet (paramagnetic +540). I haven't been able to afford a sample of it... yet.
Thanks for watching!
Really nice video! Very well made :)
Thank you very much :)
I have just uploaded part three of this series - some very-hard-to-find elements so I think it's worth a look too.
Your videos are quite interesting! I like them...lots of fun too to watch!
very cool, awesome Metals examples
Thanks :)
Very short and simplified: in matter with some unpaired electrons the magnetic moment of the electrons is not cancelled out so there is a para- or even ferromagnetic reaction. In matter with only paired electrons the magnetic moment of the electrons is cancelled out so they have a diamagnetic reaction.
Fantastic video. Congratulations!
Thank you!
There are also some rare samples in part 2 for this video: 'Exotic Elements vs. Magnet'.
Part 3 is only a month or two away and will include samples I didn't expect to have access to - so stay tuned ;)
Thanks :)
I get very mixed reactions to this video but as long as the people that do like this video remembers to press like I'm more than happy. I have tried to improve some aspects in part 2 (Exotic Elements vs. Magnet). And I'm working on getting some really hard to find elements for part 3!
this video is really so amazing, a lot of metals are so beautiful! some look similars to others, bu How the heck you manage to have all those metals?! great job!
Thanks for the quick reply this was very informal to me.
It is readily available from smart-elements'com so you can get your own. I admit it is quite expensive - took some saving up for me. But I really wanted it and was lucky to find it for sale in their eBay-shop some years ago (they still regularly have it for sale on eBay - not right now though).
Thanks for watching :)
Short and simplified: It is because of unpaired electrons. Paired electrons cancel each others magnetic moments - unpaired have a magnetic moment. The more unpaired electrons - the more magnetic moment. Many metals have more or less free electrons and therefore a magnetic moment.
That was fun, watching somebody touch magnet with metals for minutes :)
What a great vid :D thanx for sharing your awesome collection!
Tom Cummings Thanks :) I am saving up for part 4 of this video series. The last elements are quite expensive :/
It's fun to see how rare earths, basically Europium and upwards, start to atract the magnet more and more as their atomic numbers grow as more and more electrons are unpaired and contribute to the growth of the magnetic permeability.
Yes. Check part two of this video serie: 'Exotic Elements vs. Magnet'. I'm planning sort of a remake of this video with the rare earth metals and their oxides in a more sensitive setup. Stay tuned!
Coming in part three. Too expensive to be my first priority ;)
Amazing video!
Great video. Well done!
Depleted uranium is sometimes for sale - usually on the US eBay (in the US up to 15 lbs is allowed without a permit). Unitednuclear'com also used to have some for sale but they seem to be out of it.
The rare earth metal set can be bought on smart-elements'com.
