Exotic Elements vs. Magnet | Platinum Group! | Part 5/6
HTML-код
- Опубликовано: 25 авг 2024
- How does platinum react to a magnet? Time for part 5 of my series on how elements react to a magnet. This time the whole platinum group is thoroughly tested with some improved methods. Do I manage to confirm the official values for magnetic susceptibility? Hope you enjoy the video - as always a lot of work was put into it.

You guys wanna know how dedicated this guy is? I just looked up where he gets his samples from, and a 1 gram pellet of Rhenium is $40! The amount of money this guy sinks into the material for these videos is definitely worth a like! Major props, Brian
Rhodium is $700 per gram.
I love how this video makes a clear documentation of the scientific method and the mathematical analysis of the results. More science on youtube needs to have this kind of rigor. I loved the video, good job!
SoopaPop
Yep. This guy is good. I was aware of the magnetism of cobalt, iron nickel and gadolinium, as a result of experimentation with my element samples. But this floating test was a great idea that illustrated magnetic properties of many other elements that, I think most of us were probably unaware of. None of this was taught in my school. I graduated high school thinking that only iron would attract magnets! Lol
Heck yeah, I wanna see part six!
+Firefox - you obviously didn't watch the whole video.
Wood 'n' Stuff w/ Steve French You must not have.
Brandon Clifton - No... I watched the entire video. Including the part where he asked if we want a 6th part. Did you?
I'm a firefox.
Cyanide and Happiness reference.
There are only rubidium, strontium and tecnecium in the rest
Amazing how accurately one can analyze elements and their properties with relatively simple and inexpensive equipment. Knowledge truly is power when wielded properly.
Ruthenium is a fun element. When I was in school, we used some with an organic ligand to make a photoluminescent compound which would be quenched by diatomic oxygen. We embedded some in clear silicone rubber and could measure dissolved oxygen content in water by reading the intensity in response to excitation by a blue LED. It was my second favorite project in that series of labs since it brought together so much chemistry and physics.
Nice experiment indeed. But I've got to ask: What was your favorite then?
Brainiac75 Synthesis of CdSe nano crystals (quantum dots) via Ostwald ripening. The big interest at the time was attaching them to proteins and tumors to assist in kinetics study and improve medical imaging techniques. I had the idea of gluing a medley of various sizes to a then-new blue LED as a mean to produce a then-yet-uninvented white LED but my professor didn't think it would work. I found a few months later that another group in another university received a patent for basically the same idea (given the timeframe, they had prior art to the idea. c'est la vie. :))
ExaltedDuck Oh yes, I did come across CdSe when researching for the fluorescence video. Including the use in LEDs - bummer for you :(
I may need to make a video about CdSe in the future. But I guess its toxicity limits its availability.
Our synthesis involved benzenethiol to make the precursors. I would recommend against using that outside of a well equipped laboratory. Even just a little bit gone astray lingers for days, and its odor has a slightly smoky and pungently fecal quality. =D
@ExaltedDuck Definitely a fume hood project then.
@Brainiac75 You might try asking NurdRage if he knows of a way to synthesize it from chemicals that are available. Cd is available from poisoned (dead) NiCd rechargeable batteries and Se from the toner drums of used laser printers and photocopiers, and many dandruff shampoos.
Very interesting. I don't know that I've ever been aware of the properties of paramagnetism and diamagnetism. If so, I've long since forgotten about them. Thanks for teaching me some awesome stuff!
I've never seen a video from you that wasn't worth a like.
Agree
Thanks for your continuous support, Ben. Didn't recognize you at first with the new profile picture :D
Ben Landvatter
i am screaming with joy inside
you watch him too? weird lol.
🤣🤣🤣🤣 same here
Ya I find this stuff everywhere going to be purchasing bulk magnets 🧲
Many years ago when I was a chemist I set up a method to measure diamagnetism using a four figure scale. We had a U shaped piece of plastic machined up and at the top of the U we placed two powerful magnets that were attracting each other. This set up was then put on the scale and the scale zeroed. The sample was put in an NMR tube and slowly lowered down in between the magnets. The maximum reading on the scale was proportional to the diamagnetism of the sample. I recall it being surprisingly accurate I'm guessing because the magnetic flux between the two magnets was very high. I can try to draw the apparatus if you need.
So the scale is holding the weight of the magnets too? I guess two smaller magnets with opposing poles would make a powerful magnet field for small samples inbetween. Thanks for the suggestion :)
Yes, the magnets and the frame holding them apart are all on the scale. I was using a 4-figure balance which has a maximum tare weight of 500g (IIRC). That's easily enough for two decent sized magnets. I seem to recall the magnets were about 30mm diameter by 10mm thick. This was years and years ago though so we were probably limited in what we could get hold of. I would imagine the parallel field lines in this set up help with measuring diamagnetism as the generated force would be entirely perpendicular to the sample. An NMR tube is perfect for the sample too as it's very thin glass and you can buy holders for them. I was measuring powders of metal containing complexes, solid metals might be better just stuck to the end of a stick :-)
OK - my scale only holds 20 g in all, so it limits the size of the two magnet too much. But I may try to lower the two magnets with opposing poles and having the sample steady on the scale - should give the same result.
That's some good lateral thinking. Perhaps you could crowd fund a set of accurate scales. Looks like you can get a 0.1mg accurate scales fro
I have those same gold spoons! The plating is so thin it started wearing away almost immediately. Thanks for the video. I like seeing large hunks of pure elements and getting a sense of their mass properties.
i absolutely love the fact that you are super scientific but still use the same (great
) interlocking brick system as used in toys
Hehe, I'm not a scientist but a science fan. And why not use Lego for the experiments - it's so universal :) Thanks for watching!
yeah. i hope my videos reach that quality. and you are a scientist as long as you record it. (d2rormqr1qwzpz.cloudfront.net/photos/2015/12/15/83986-83931-05-mythbusters-expressions.jpg)
Thank you so much for providing amazing videos for over a year as I have watched you since 3k or less! Your videos are amazing and are very interesting. Thanks for the Christmas gift!
your vids are so informative and most importantly... not boring!
Really cool what you're doing here. Great to see these measurements done in a way that makes sense as to what exactly the measurements mean.
"Oh, sh... plashing water!" ;)
lol i was curious as to what this comment was about now i know lol
Ah, I see you've changed your profile picture.
Great information, interesting how metals in the same category have such diverse results.
Thank you!! I can't tell you how many times I've had to correct people who believe that Platinum and PGMs are not magnetic. Especially among the buyers of ore and processed metals i deal with.
I kinda like how you actually updated the periodic table to the new names of the artificial elements.
Yep, that's one of the changes happening in the 4 year span of this video series so far. Thanks for watching!
Super informative! and the caption help me understand much better. Thanks!
No problem - thanks for watching :)
Thank you for this.
Yes, part 6 please!
You weren't centered on the gold push/pull test, CLEARLY. I should think it makes a difference? At any rate, a brilliant show and thank you very much.
It does look a little off center. I may have been able to get a couple of milligrams more out of the gold sample with a better centering. Thanks for watching :)
I now understand what is para and dia. WIKI blows my mind away and your experiments blow it back again. (Plz let part 6 shown on RUclips)
Yeah.. part 6. We all are waiting.. Keep up the good work.. We all are magnetically drawn to your channel..
I greatly appreciate the detail you put into each video. You also make sure there's a ruler for your viewers reference. You always put the bottle of the metal your testing next to the test. You even put a Lego finish sign at the end of the speed test. Thanks for taking time to add the little details that make all the difference!
Thanks for noticing the small details. I believe you would like my other videos too, since I do try to put a lot of work and thought into all of my videos. No daily or weekly mainstream videos from me ;)
Yes, I would love to see a part 6.
I have learned more about elements from this series than I have in public ed and uni. Wonderful info!
this has been great I caught all 5 of the vids at one time.. please do more if you can.. these were very very interesting.. makes me want to collect all of the elements of the periodic table for a display..
liked the information about each element as you tested their magnetism
Super cool that you are saving up all this money and not asking for money
This is concisely explained, and should be taught in all schools.
You have one of the best youtube channels i've seen. Thank you for what you do.
Thank you very much! Much more to come. I'll try to lift it to a new level in 2017 :)
Nobody does this. I have a feel for this group of elements now.
Thank you
5:30 - Thank you very interesting table
Amazingly thorough research...
I can't understand anyone giving a thumbs down to a vid that is just the presentation of raw facts? As a friend of mine would say, "haters gonna hate".
I love these videos in general but for me the best part is the end where you let loose and have fun
Thanks! I try to balance being serious and entertaining in the same video :)
You are entertaining and adjucatina and that's why I watch your vedio s from Iran with VPN
Iran! Don't remember ever having a comment from your country. Great, that you have found a way of watching RUclips :)
**Going to the jewelry**
I want 3 Au's please.
Fun joke
あうあうあう
Au. Au! Au!! Is that better? ;-p
@@RWBHere RHODIUM
my god, this is truly amazing! thank you so much for such an awesome time of learning about the elements. :)
please do part 6!
Thank you very much :) Part 6 should be possible.
I can not wait to see part 6 and beyond. :D
I was so excited to see part 5 show up, can't wait for part 6, and maybe 7 and 8
super cool stuff. This is the first of your videos that I've seen, and I'm very impressed.
Nice - thanks for watching :) More to come.
I knew an old man who died. No one cared a lot about him but he was friendly. His family just decided to burn his house along with his belongings, but gave me permission to save a few things if I wanted. He was very into elements and I found various containers with elemental symbols. I took a few of these home, as they were marked Ag and Au on them. Selfish me? No. His family didn't care about his stuff, so now those elements live with me :)
if you did part 1,2,3,4,5 you must do part 6
i'm not fun of magnet stuff but hey a good video is a good video, it does not matter what it's about really i think
Wow,all the time it took you to film these experiments, and I've just gorged myself on them in one go. Brilliant, thanks. 😁
It's always fascinating to see the 6 different kinds of magnetism. In another video maybe, could you explain how superparamagnetism works for those who may not know what it is? Normal paramagnetism is my personal favorite kind since it makes paperclips stick to other paperclips. Diamagnetism is cool though as well since it levitates things. Why it actually happens though is really goddamn complicated
Magnetism sure is complicated and difficult to explain. Hard to apply our daily logic to the quantumm mechanical effects from electrons :\ I may give it a try in the future - thanks for watching!
What about Antiferromagnetism? I saw in a website that Chromium does that, but I'm not sure, since your table contradicts that.
Antiferromagnetism has a bunch of atoms or domains of atoms generating magnetic fields opposite to the atoms or domains beside it, cancelling them out and producing no net force. And example is Iron III oxide: Ordinarily it is antiferromagnetic. You can heat it to above it's Néel temperature though, and it will become paramagnetic
Gi tirado Chromium is interesting since its Néel-temperature is just around room temperature (where it changes from antiferromagnetic to paramagnetic). I may have to try to cool/heat chromium in a future video to see if I can spot any changes in the magnetic susceptibility. In my table I used the value from CRC Handbook which should be around room temperature.
Once again, top quality work. Your patience is way better than mine. I would have gone mad if I had to repeat each test ten times! Have a Merry Christmas, New Year and put your feet up for a well deserved rest :) Cheers.
Hehe, it's only 90 test in about an hour. Nothing compared to the probably 70 hours put into this video in all... Merry Christmas and Happy New Year to you too. It's been a good year.
Brainiac75
Oh I fully understand the extra time taken in making the "whole" video, but still, doing those tests Ggggrrrr. All the best :) Cheers.
Thanks for showing thoughtful fun with magnets ...
Rhodium: yeah i'm attracted to the magnet
Palladium: *i am speed*
Really nice demonstration. Some inexpensive techniques for scientific investigation of a very interesting property of materials, which anyone can do at home.
Lol the spoon at the end killed me
Fascinating .. Wondering how to capitalise on this knowledge!
Clever, clear demo. I would love to see part 6!
I love how cleanly you edit your videos mate
Alexander Martínez Pasek thats why it takes a lot of time to produce a video like this, quallity matters.
The creativity with legos and models you used to measure magnetic force are pure genius. Oh and of course we want part 6 :)
This series is fantastic. LOVE the chequered flag in the stop watch test.
Excellent video!!! Exactly what I was looking for. I am thinking of two applications. One is to separate precious metals from automotive catalysts. Pulverize, swipe a magnet and voila! Another one for investors - to authenticate gold and silver coins and bars, which are prone to be counterfeited with, for example, tungsten.
I would love to see part Six!!!
Thanks for sharing your research with us.
A great demo with great info
I watch your videos before I go to sleep. I find the information is absorbed well before sleep. very interesting videos. I really enjoy your simple and effective presentation of your videos, it's a breath of fresh air compared to some other science channels. This seems more honest and less cringe. keep it up señor I do enjoy them. You do a great job. I'd like to see more videos on the physical properties of magnets in electrical equipment. Merry Christmas!
regards
Dan
Thank you very much, Dan! Much more to come and Merry Christmas to you too :)
Another exotic elements video, Waited 1 year, and it was definitely worth it ;)
The mithril sample seemed very attractive!
Yes I do like this video I am going to have to go back and watch the first 3 I came across this looking for something else and it peaked my interest and curiosity. I'm glad I stopped by.
Well. Just saw the whole series as well as 2 other videos. I look forward to your future videos. :) Subscribed! Very high quality content.
That's awesome. Welcome aboard :) Much more to come.
Love this video. You did a great job. Thanks for this info. Who would have guessed so much fun can be had exploring metal properties. Awesome.
Really exciting and excellent experiment
Part six please love your element vs magnet videos
:D
This is really cool, and the diamagnetic stuff blew my mind. Good work!
Thanks for watching :)
i love the way you said hi at the start of the vid
Well, that's a good start :D
Wow even youtube gives me christmas presents! Great video as always, Brian. :)
Hehe, this video is my little christmas present to you all. Thanks for always watching!
I always enjoy your videos and the detailed physicist's sort of explanations. Myself I am an electrical engineer and I always crave expanding my knowledge of how things work and material properties. I learned something new today about silver when watching your videos as an example. Many thanks. And Merry Christmas to you.
You have great videos. They're a pleasure to watch.
Yes, Part 6 would be wonderful!
I randomly stumbled onto this channel. Very cool stuff, subscribed.
Nice :) Welcome aboard!
excited for part six
I like your samples of elements. Something I've always wanted to collect myself.
The best christmas gift: one new creative video from you :D
Always love to see these videos once in awhile would love part six
Nice. Totally looking forward to part six.
You have the most amazing channel . Thank you
perfect! as always ! love to see the part 6
You didn't have to ask for a thumbs up. This was worth one imo
I DEMAND PART SIX!
Fascinating as usual.
Your video really deserve to be best video regarding meassuring the intensity . . Most I would say sphere process you shown is best way to make the perfect reading to element attraction 🤩🤩🤩🤩🤩🤩👍🏻👍🏻 nice outstanding video
part 6 is gonna be fun
I would love to see it braniac
I'll make it when I buy some of the remaining elements. Thanks for watching!
Fantastic episode continue with more please
Bravo , just Bravo mate. keep it up !!!! Very nice stuff and amazing narration!!!!
Thank you very much :o) Much more to come in 2017.
Rhodium is also used as a protective plating for platinum, white gold, and silver jewelry
I enjoyed seeing these videos, I'm thinking there are other experiments to try?
Doing them all again but at different temperatures (where appropriate/possible) also at different pressures, near vacuum and several atmospheres, might need to construct suitable test apparatus😊
Looking into Curie points possibly being the main theme🎉
Rhenium's a funny one - although the metal itself is very resistant to vaporisation, its recovery from the ore involves the distillation of the easily vaporised rhenium heptoxide.
how didn't you have any problems with your phone near that giant magnet?
Nevan's lab phones do not have magnetic moving parts, so it should not be a problem
minecrafter9099 right ok
if that camera stay long enough near the magnet, the camera autofocus, vibrate motor, speaker will get messed up because the magnet inside it could changed polarity
It is a very basic smartphone. No compass or any of that fancy stuff :D The waterbath is probably the biggest danger for it ;) Thanks for watching!
Yep, I always keep the camera at distance and zoom in. The magnet can mess with the focus system.
YES!!! Part 6!!!! Tungsten filled gold bars!!!!
Keep up the good work and Merry Christmas
Excellent science display, thank you :)
there is far less on youtube on diamagnetism and paramagnetism than I ever thought there would be. there are many more vids on magnetism and electromagnetism. it would be awesome if you made more videos. electrodiamagnetism is an idea I'm very particularly interested in lately. I think if you could refine a bismuth sphere well enough and electrify it to very high voltage the results light be pretty cool.
oh. anyone else thought that this was a cody's lab vid in there sub box?
yup drinking heavy water !
I'll take that as an compliment :D
It was :)
Genatari Kralc, did you mean to say '....Cody's Lab video in_ that there_ sub box', which is colloquial? Maybe it was meant to be, '...Cody's Lab video in _the_ sub box'? Or was it '...Cody's Lab video in _their_ sub box'? Your question is unclear; probably because either speech to text or autocorrect messed it up. Thanks for the clarification.
RWBHere long time ago. Probably the
yaaaay the periodic element table has all the names!! good job!! you got a sub
Thanks! Welcome aboard :)
Definitely hoping for a part 6. Didnt even know diamagnetism was a thing before your videos
Part 6 will come sooner or later - I just haven't got more elements to show right now. Have a little patience and thanks for watching :)
Absolutely superb videos!
We are waiting for the part 6 !!!!!
I really enjoy your videos!
