Exotic Elements vs. Magnet | Part 1/4 | Uranium and 40 other metals

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 series.

I have had quite a lot feedback suggesting that I should have put the magnet on a string or scale so smaller effects would be visualized. I use this in newer parts of this series:

Part 3: http://www.youtube.com/watch?v=0-ex-C...
Part 4: https://youtu.be/I2pmV_jjC7c

I may at some point redo this video with a stringed magnet, but with 41 metals it is quite a large project :|

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...
