i remember i studied in my 10th standard, not all metals attract to magnet., metals named nickel, cobalt will attract to magnet and their ores too, why dont other metals attracted to magnets ? i remember their symbols also Ti - Titanium (hardest metal) Fe - Iron Co - Cobalt Ni - Nickel Cu - Copper Gd - Godolinium (dont know of this one so, i improved video quality amd zoomed to see the answer) W - Tungsten (used in bulb filaments) i have a question already mentioned, someone please explain Thank you :)

[@mrxmry3264]

Magnets will attract iron, cobalt, nickel and gadolinium.

[@physicsfun]

You are intelligent ❤️ Not all metals are attracted to magnets because of the arrangement of their electrons at the atomic level; only certain metals, like iron, nickel, and cobalt, have a specific electron configuration that allows their magnetic fields to align easily with an external magnetic field, making them strongly attracted to magnets, while most other metals do not have this property and are only weakly attracted or repelled by magnets. Key points to remember: Electron configuration: The way electrons are arranged around an atom determines its magnetic properties. Ferromagnetic materials: Metals like iron, nickel, and cobalt are considered "ferromagnetic" and are strongly attracted to magnets because their electrons tend to align in the same direction. Diamagnetic and paramagnetic materials: Most other metals are either weakly repelled (diamagnetic) or weakly attracted (paramagnetic) by magnets due to their electron arrangement.

​@@physicsfun woah ! i got it very well sir, none of the teacher ever explained me this in such detail, thank you so much for improving my knowledge sir, i think you are professor in university i will try to do a good physics high energy particle research internship under your guidance❤❤

[@snoutysnouterson]

Titanium is not the hardest metal. Tungsten is.

Finally a video that's longer than 10 minutes!

the music track; Cyberpunk Synthwave - Black Rainbows. very nice track

Glad you enjoyed

Truly the magic of science.

Glad you enjoyed The most beautiful thing we can experience is the mysterious. It is the source of all true art and science.

The "I LOVE YOU" card is clever. Makes me want to go work one out, for birthday cards, or whatever. It would be interesting to see the resultant patterns, if they are apparent (probably not), uncovered. To me, the hearts are obvious on the open card, the lettering, not so much, but building them, they would more likely be. I knew a guy once that had done so much editing on reel to reel tape, using his fingers to wind back to the beginning of sentences, etc. that he became proficient not only at understanding the speech in reverse, but could actually speak normal sentences, recording them, playing them back in reverse, and they were understandable. Three, not that there is anything wrong with it, just that it gets monotonous, maybe get a few versions and change it up with each new toy, or occasionally throughout the video. You asked. I'm not sure I understand the totality of the physics going on in the reverse hourglass. Maybe some attractive or frictional/rotational forces between the beads, keeping them from just passing through the neck, at the total passage diameter. Or more likely, the reverse flow required of the liquid being displaced through the neck, as the primary retardant driver? The geometry of the phenomena makes me guess the latter, especially at the lower separation interface. It looks like more than one, as well. Interesting. The suspended ornaments in the 'liquid' is super clever. Had you not shown that one, I'm not sure I would have come to that conclusion, especially if you had pointed out that they were truly stationary, with no buoyancy driven movement. I can think of some other ways to do that, but not ones where you could chose placement, and have them truly stationary, negating variations on that same theme. Probably people smarter than me on the subject could, though. Using the hydrophilic material so that the index of refraction was near perfect was genius. I wonder how many of those types of illusions were thought up out of the blue, and how many were "lucked into"? When you do studies, you find that MANY materials, chemicals, etc. were the outcome of happy mistakes. I saw acoustic levitation demonstrated quite a while ago. Great implementation for a toy version.

[@physicsfun]

You are intelligent 👀 Time's Up: inverse of the sandglass- tiny plastic beads are less dense than the water and thus ascend to the top of the container under the influence of a buoyant force in accordance with Archimedes' principle. This timer takes almost exactly 6 minutes to complete shown here at normal speed for the first half of this video, and the second half is condensed to 24 seconds in time-lapse.

[@MrJdsenior]

@@physicsfun I just skipped over the obvious part. I was talking about the action through the neck, which was what struck me as not what I expected. Retired engineer, so I know just about enough about physics to be dangerous, but not much more.

We need to understand science and excel in it to sustain

[@MrJdsenior]

Sustain what. exactly?

[@Reach3DPrinters]

@@MrJdsenior sustain survival. We are accelerating the consumption of easily accessible and convertible resources, on the earth, for our needs. The only way to sustain our survival as a species, is to either innovate, or have a mass die off, which almost happened in the 20s, when nitrogen and phosphorous rich bird poop, being shipped in as fertilizer for food crops, was depleting, and costs were sky rocketing and food began to get really expensive. A nazi scientist named Haber, figured out how to extract nitrogen from the air and create ammonia. He also created the gas that killed millions of people in the holocaust. So even though his invention is partly responsible for millions of deaths, its likely he is also the reason why a bulk of our civilization exists today. This was one hurdle, from population increase, showing that easily accessible resources will run out, and the only way to prevent mass die off, is to innovate to sustain pop growth and manage resource consumption and use and access, using technology. We have open Pandora's box. The only way to sustain, is to push forward. If we stop pushing tech forward, die off will happen. Its part of the natural system. When life explodes in an ecosystem, life multiplies until ecosystem is depleted, then die off to re balance. So... we have to modify our ecosystem to convert unusable resources into usable ones, and integrate a cycle to maintain population.

Pity all my Xmas presents are done already :D Got the hovering magnet lamp a couple of years ago to my parents, probably after one of your videos, always a success when visitors come at home :) And yes, I admit I immediately regretted I didn't get it for myself.

"Holiday decor" is very interesting.🙂

i think if i had that water bottle at work, i would never get any work done because i'd be playing with it all day

[@SandraCat22]

0:10 for those who don’t know, Bismuth is the active ingredient in Pepto Bismol… don’t believe me? Check the label of a Pepto Bismol box or bottle.

Rate Background music on a scale of 1-5. Why not 0-5? You're taking away an option.

[@prophetofducks]

titanium (Ti) iron (Fe) cobalt (Co) nickel (Ni) Copper (Cu) Tadollnium (Gd) Tungsten (W)

[@arnab_blue]

No need to zoom, in desktop all are visible... 😅 anyway I didn't know about what Gd & W stand for... Fe, Co & Ni attracts to magnet for sure...

[@physicsfun]

You are intelligent Here are seven samples- 1 cm cubes of 99% pure elements: Ti (titanium), Fe (iron), Co (cobalt), Ni (nickel), Cu (copper), Gd (gadolinium), and W (tungsten)- Although magnets are familiar objects, the physics of ferromagnetism is very complex and is described by the quantum mechanics of intrinsic particle spin and the specific electron configurations of solids and molecules.
