Exotic Metals vs. Magnet (including uranium)

I believe this video is unique. I haven't found a video on YouTube 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.
Video responses with magnets versus other metals not featured in my video are more than welcome!

Hi. Welcome to my video on how magnets
reacts with a lot of different elemental metals.
I've made this video because a lot of
people seems to know very little about
how metals reacts with a magnet. I haven't
been able to afford all available metals
yet but will expand in the future
so I can update this video.
Some of the metal samples are quite
small due to cost so I'll use a
magnet of similar size.
It's tiny but has the power to reveal
any attraction to the metals.
Let's start with a simple one: Iron.
Iron is ferromagnetic meaning that it
will not only be attracted to a magnet
It can be magnetized in itself.
So can nickel
and cobalt.
Gadolinium is actually
also ferromagnetic but only below
20 degrees celsius.
Above 20 degree celsius it turns
strongly paramagnetic.
This means it still attracts the magnet
but it can no longer be a magnet in itself.
Now let's take a look at some light weight
metals. They may be light but they are
quite potent.
Lithium will etch your bare skin
Beryllium in dust form is among the most
poisonous non-radioactive elements
and magnesium will burn extremely
hot and bright.
Next up I will quickly go through from some
more ordinary metals.
Okay - we are almost a third of the way...
These cylinders have the same dimensions
but the weight difference is hard to believe.
Here we have what could be called the twins
of metals. They are very difficult to
separate, so zirconium samples will always
contain some hafnium and opposite.
How about some toxic ones?
This is mercury with some little glass
fragments floating around on it. I haven't
figured out how to filter it yet.
Now for some more of the transition metals.
The antiferromagnetic and beautiful chromium.
The brittle manganese.
The superconducting niobium.
And the hard-to-melt molybdenum.
From a metal with a high melting point to one
with a very low one: Gallium.
Known for melting in your hand.
Moving on to some metals that most
people never see in real life:
The lanthanides - also known as the
rare earth metals.
Neodymium is one of my favorites. It's used
in my powerful magnets and green lasers
but in pure form it is not much fun...
After having found some more metals
that visibly attracts the magnet
let's take a look on the metal that
repels a magnet the most - in other
words the most diamagnetic metal: Bismuth.
It is still a very weak repulsion but it
can be used for diamagnetic levitation.
Finally I have the infamous uranium.
So - the conclusion is that the magnet
will stick strongly to 4 of my metals
at normal temperatures but a total of 10 metals
can have enough attraction to lift the magnet.
Feel free to comment, rate and subscribe.
There will be a part 2 when I have more metals.
Thanks for watching!
Darkness is coming...

what is the name of the song played at the end.

@RyviusRan:

It's 'Darkness is coming'. I put full credits in the description for this video.

[TisseTuss]

@brainiac75 Im from sweden :) one question though, can you really get uranium from eBay?

[brainiac75]

@TisseTuss:

Yes! There are a handful of US sellers but not all will ship to Europe. I just did a search for 'uranium metal' on the UK-version of ebay and found a 1 gram sample for $110 that can be shipped worldwide. Don't ask me what the swedish customs will say if they open your package though. I have no idea.

[Heart111ful]

@brainiac75 what is the reason of their high, low or medium force of attraction or repulsion with the magnet ?? i have a little idea about that, but want to know more to ensure.

[brainiac75]

@Heart111ful:

Start with googling ferromagnetism.

In very short: magnetism comes from unpaired electrons in the atoms (their spin and electrical charge).

But crystalline structure, temperature etc. also play a role: Heusler alloys are ferromagnetic even though there are no ferromagnetic metals in the alloy! So it's complicated...

awesome jeg er også dansker xD

[NYCTruthAdvocate]

Very Nice Video....Very Educational...hope the PUBLIC WAKES UP & SEES WHY CHINA IS MONOPOLYZING THE WORLD MARKET ON RARE EARTH METALS...THINK OF THE ENDLESS APPLICATION POSSIBILITIES...keep up the good work!

[happylambs]

Fascinating! Thanks for doing it.

[MrTrykster]

i loved this video SO MUCH. i will subscribe to you now

[SuperMagnetizer]

Excellence Unveiled! Thanks for your work in making this! Excellent presentation!

[mrmagnetsarecool]

Yah! new video, thanks!

[aleamundi]

Good work as always! :)

[IroniMan100]

Nice video! Its so cool to see how they react to eachother.

@brainiac75 Oops I didn't see it in the description last time I checked thanks for the info.
