Exotic Elements vs. Magnet | Platinum Group! | Part 5/6
Вставка
- Опубліковано 21 гру 2016
- 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!

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.
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 🧲
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!
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
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!
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.
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.
your vids are so informative and most importantly... not boring!
Thank you for this.
Yes, part 6 please!
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 was so excited to see part 5 show up, can't wait for part 6, and maybe 7 and 8
perfect! as always ! love to see the part 6
Wow,all the time it took you to film these experiments, and I've just gorged myself on them in one go. Brilliant, thanks. 😁
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..
"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.
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.
Super informative! and the caption help me understand much better. Thanks!
No problem - thanks for watching :)
Yeah.. part 6. We all are waiting.. Keep up the good work.. We all are magnetically drawn to your channel..
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.
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.
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.
love to see part six! loved the part at the end too xD
Always love to see these videos once in awhile would love part six
Great series. thank you kindly for doing these.
Fascinating as usual.
I can not wait to see part 6 and beyond. :D
I have learned more about elements from this series than I have in public ed and uni. Wonderful info!
The best christmas gift: one new creative video from you :D
Fascinating .. Wondering how to capitalise on this knowledge!
Clever, clear demo. I would love to see part 6!
Another exotic elements video, Waited 1 year, and it was definitely worth it ;)
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.
Nice. Totally looking forward to part six.
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 :)
I really enjoy your videos!
You have great videos. They're a pleasure to watch.
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.
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.
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 ;)
Absolutely superb videos!
Keep up the good work and Merry Christmas
This was awesome!! Thanks for doing it!
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
A great demo with great info
This is a really great channel. Thanks for your hard work!
Thank you very much for your support :) New video just uploaded.
Yes, I would love to see a part 6.
This is really cool, and the diamagnetic stuff blew my mind. Good work!
Thanks for watching :)
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)
Wonderful job, man. Congratulations.
You have the most amazing channel . Thank you
Great information, interesting how metals in the same category have such diverse results.
Great work!!
liked the information about each element as you tested their magnetism
Fascinating video!
This series is fantastic. LOVE the chequered flag in the stop watch test.
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!
Great vid, and really creative tests!
Bravo , just Bravo mate. keep it up !!!! Very nice stuff and amazing narration!!!!
Thank you very much :o) Much more to come in 2017.
I love this! Thank you!
The creativity with legos and models you used to measure magnetic force are pure genius. Oh and of course we want part 6 :)
Really exciting and excellent experiment
Thanks for your hard work
I randomly stumbled onto this channel. Very cool stuff, subscribed.
Nice :) Welcome aboard!
Thank you, this was very interesting! ☺️
yaaaay the periodic element table has all the names!! good job!! you got a sub
Thanks! Welcome aboard :)
Awesome job, thank you for your time and work, keep going!!!! PEACE.
Yes, Part 6 would be wonderful!
Really cool!! Thanks for the upload
Love the videos!
thanks braniac75! your videos make me feel great.
Really nice demonstration. Some inexpensive techniques for scientific investigation of a very interesting property of materials, which anyone can do at home.
Great video, Brainiac!!!
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 UA-cam)
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 :)
Thanks for sharing your research with us.
I like your samples of elements. Something I've always wanted to collect myself.
Very nice, well done Thank You !!
Perfektné a zaujímavé🔆

Lol the spoon at the end killed me
you are awesome my friend! one of the best youtube science channel!
Thanks for your continuous support :)
This is pretty neat.
Superb and very interesting Video!
excited for part six
This is concisely explained, and should be taught in all schools.
you have a very good quality videos, congrats man.
Thank you very much - much more to come :)
love your videos they are very amazing
Great videos!!!
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!
So good video! Good luck! I want more :)
