How about testing a solution of a gadolinium salt in water? Then precipitating pure gadolinium silicate and melting that into a glass bead?

I just woke up and, strangely, I was asking myself if glass can be magnetic. I absolutely love this.

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.

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

Your content is always exceptionally intriguing! Oh and your video editing skills are fantastic too!

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).

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.

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.

10:08 hmm, yes, the floor here is made of floor

What a great video. Just amazing.

love the color of the Holmium bead

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.

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.

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.

Some steady hands you got xd 9:57

I never thought that glass doped with a paramagnetic element could be more attracted to a magnet than iron doped glass...

YEAY! ANOTHER VIDEO! 😁

#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!

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.

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.

I also collect uranum/ vaseline glass. Looks awesome under black uv light

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.

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

Well done, interesting video.

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.

Very cool!

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?

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.

Can you test if they react to light any differently while in a magnetic field?

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.

@smartelements

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.

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.

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

what is it with lanthanides and strong magnetism?

I think these glass beads are so cool.

It was interesting cheers for the info

What are the differences between the metals used against light or UV rays and are there any that block flashing like in welding

I always thought The Simpsons were exaggerating the green glow, but maybe Springfield nuclear uses UV lights at their plant lol.

Maybe do the same test but see what glass beads repells the fastest

Nice video :)

Amazing!

I was expecting the Gd bead to go flying onto the magnet and shatter in the "race" test.

I believe that water drag isn't that significant in this experiment since the velocities involved are way smaller than the terminal velocity this boat should have with the beads. Maybe it's just the concentration of each metal in the bead that causes the ferromagnetic ones to be less attracted than the paramagnetic.

Have everything float on Mercury or something like Mercury

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..

Physically speaking, it is anomalous that the heavier beads displace faster than the lighter beads; given that the weight of the beads directly influences the height at which the boat submerges into the water, thus serving as a factor in the direct proportionality of surface area and the drag that boat should experience, theoretically. This was not witnessed in practice. From a physical chemical perspective, what we witnessed in the video is what likely should occur because of the intermolecular forces involved amongst the polar compounds that take part in the experiment; Not just the bead and the magnet, but also water are polar. Water is the medium that was used in measuring displacement versus time. The countless attraction-repulsion interactions between each individual water molecule, whilst keeping in mind that as the bead on board the styrofoam boat displaces across water there are also momentary interactions between water molecule poles and the magnetic bead which essentially compensates for the resistance that should theoretically be experienced. Almost like when you visualize the energy and time it would take for one person going up the stairs versus the time and energy it would take for a larger person riding up the escalator.
