Q & A
What is the main focus of the 'Science Max Experiments at Large' series?
-The main focus of the 'Science Max Experiments at Large' series is to perform everyday science experiments on a larger scale, exploring the principles and effects in a more dramatic and visually impressive way.
What type of magnet is used in the experiment to demonstrate magnetic levitation?
-A neodymium magnet, also known as a rare earth magnet, is used in the experiment to demonstrate magnetic levitation due to its strong magnetic properties.
What are the two poles of a magnet and how do they interact with each other?
-The two poles of a magnet are the north pole and the south pole. When like poles (north-north or south-south) are brought together, they repel each other, while opposite poles (north-south) attract each other.
How does the presenter demonstrate magnetic levitation?
-The presenter demonstrates magnetic levitation by using two magnets with their repulsive poles facing each other, causing a coin to float in mid-air without any physical support.
What is the significance of the Earth's magnetic field in the context of the video?
-The Earth's magnetic field is mentioned as an example of a giant magnet, with north and south poles, and is used to explain the concept of magnetism and the attraction/repulsion of magnetic poles.
What materials are attracted to magnets and why?
-Materials that are attracted to magnets are called ferromagnetic materials, which include iron, nickel, and cobalt. They are attracted because their atomic structure allows them to align with the magnetic field of the magnet.
How does the presenter attempt to levitate himself using magnets?
-The presenter attempts to levitate himself by standing on a platform supported by ring magnets. The magnets are placed on shafts to keep them aligned and prevent movement, which is crucial for maintaining the levitation effect.
What is the result of the presenter's first attempt at levitating himself with magnets?
-The presenter's first attempt at levitating himself with magnets is partially successful, as he manages to levitate slightly but not completely. The magnets slide around and he does not achieve full levitation.
What is the science behind the levitating pencil experiment?
-The levitating pencil experiment works due to the repulsion between like poles of magnets. When the pencil is placed against the wood, the magnetic field creates a balance that allows the pencil to levitate without any physical support.
How does the presenter address the challenge of balancing two repelling magnets?
-The presenter addresses the challenge by using ring magnets with a shaft through the center to keep them perfectly aligned. This method is similar to the one used in the levitating pencil experiment but scaled up for the human levitation attempt.
What is the outcome of the presenter's final attempt at magnetic levitation?
-The presenter's final attempt at magnetic levitation is successful, as he manages to levitate on a cushion of magnetic energy with the help of a larger board and more magnets, achieving a stable levitation effect.

Transcripts
have you ever done a science experiment
and wondered what it'd be like if you
did it big
i have
[Music]
my name is phil and i take your everyday
science experiments and do them big
this is science max experiments at arch
facts
it's time to get stuck on magnus what's
our attraction to magnets what's their
attraction to each other and can i use
magnets to levitate and float in the air
all on this episode of science facts
experiments at large
[Music]
greeting science maximize welcome to
science max experiments at large my name
is phil and today we're going to be
looking at the power
magnets you see
magnets are fun things to experiment
with because
they are
really okay they're really interesting
um
this magnet that i've got here is a
neodymium magnet
or a rare earth magnet it's one of
one of the one of the strongest magnets
you can
get um
a magnet is an object that is attracted
to
anything that is feral magnetic which is
iron nickel or cobalt and
mag magnets are interesting because they
have two sides there are two
uh oh there are two poles i'd show you
but i can't get the chain
off
hold on
there are two
oh no
there are two poles to every magnet uh
just like the earth there is a north
pole and a south pole that's right the
earth is a giant magnet so
if you take kitchen magnets you'll find
that there's two different poles i've
written north and south on these ones
they don't normally come like that if
you put the north and the south together
they stick but if you put the north
north or south and south together they
repel they repel see they don't want to
go together at all and you can force
them together if you want but if you do
they will spring away the second you let
them go
but when magnets repel each other i find
that some of the most interesting stuff
check this out this is just a small
container and i've got a magnet in here
and i have a loonie attached to it so
that it fits nicely in the container
like that
for the top i've attached two magnets
together and i have another coin on it
and if you put them in there i've made
sure that the two poles repel each other
which means this magnet will just sit
there and float
magnetic levitation very interesting and
you can pop the top on that if you want
and just carry around a levitating
magnet now there's a couple fancier ways
you can levitate stuff with magnets this
is just a wooden frame i've made this is
completely not necessary you can use
just about anything in your house a desk
lamp works really well the important
part is i've tied a magnet to the end of
this arm here and this is a bolt which
is attracted to the magnet but it's got
a thread tied to it so it can't get
there
just far enough
that it will actually hang in mid air
look at that it's not attached to
anything it's just being pulled up by
the attraction from the magnet the thing
is as soon as you pull the bolt away far
enough it will lose the attraction and
it'll just fall
very cool here's one that's a little bit
more complicated
but is also really neat
this one uses disc magnets which have a
circle or a hole in the middle of the
mirror and you put two around a pencil
and then four more in such a position
that you can put the pencil
against this wood on the side and
it will just
levitate on its own you can even give it
a spin look at that and if you want to
make the levitating pencil yourself
there's step-by-step instructions on how
to build an easy peasy version on our
website
meantime we are going to max this out
magnetic levitation on science max
experiments at large but you're probably
thinking what are we going to levitate
well we're going to levitate
me at least
that's the plan that's why i'm going to
the center for skills development and
training
come on
and only only going down to waist level
this is the weirdest room i've ever been
in
where where am i what's going on
hey matt hi phil this is matt he's from
job master magnets now you guys use lots
of big magnets right that's right we do
awesome so maybe you could help me max
out this
wow you did a great job of building the
levitating pencil experiment yeah so
what's going on here exactly well all
magnets have at least a north and a
south pole right and when you put like
poles together they want to repel oh
okay so have you ever levitated a person
not yet well let's do it all right do
you think we can use these we could try
okay we'll uh put that one on the ground
and okay so north and i'll put the north
one on my foot here and then if i just
step one wait a minute if i step
stop moving if i step on that
step on the okay well first of all the
this magnet keeps sort of moving away
from me when i try to push down on it
uh what do we do how do we fix this well
we need to keep the magnets positioned
so that they don't move around when you
try to bring them together yeah because
i have to come straight down on it
though that's right so why don't we
attach this one to the floor
good idea and then we'll put a board on
this one and we'll see how it goes
perfect okay let's do it all right
[Music]
this is a magnet this is a magnet this
is a magnet
this is a shoe what's the difference to
know that you have to know your magnets
this is a donut it does not stick to
this magnet
this is a spoon it sticks to this magma
these paper clips stick to this magnet
this shoe does not
so what is attracted to magnets only
things that are ferromagnetic here's the
difference horseshoe
horseshoe magnet this one is a magnet
this one
is not
but the horseshoe sticks
to the horseshoe magnet because this
one's a magnet and this one is
ferromagnetic
only things that are faro magnetic are
attracted to magnets things that are not
attracted to magnets they're not
ferromagnetic
plastic banana
mitten sandwich magazine
no but how do you know do you go around
the world sticking a magnet to every
single thing one at a time hey ma i need
you to come over
i need to see if you're ferromagnetic no
ferromagnetic
no you don't need to do that first of
all only metals are ferromagnetic so
that eliminates all your clothing your
luncheon meats yeah magazines what have
you everything that's non-metal you
don't need to worry about
never mind ma it doesn't matter but
this clock is metal
it doesn't stick well not all metals are
ferromagnetic mainly just the ones with
iron nickel or cobalt
and there you have it now you know your
magnets
i hit the phone on the magnet there okay
uh can you hear me ma
hang up the phone hang up
hang up the phone ma
[Music]
my first attempt at levitating had the
magnets sliding all over
so the plan is to take the bottom magnet
and attach it to a big wooden board so
it won't go anywhere then attach another
plank to the top magnet to make it a
little easier to stand on
okay that is definitely attached to the
floor
thank you all right now if i just get
this lined up
oh
look at that it could totally oh wait a
minute
totally
it doesn't want to stay
a put
they levitate come on
levitate
why doesn't it want to stay
and it just doesn't
hm should i stand on it okay i'll stand
on it here we go
and
ah
am i levitating no no
hmm
so why isn't this working
well just like your pencil experiment
we need a shaft through the center to
hold the magnets in position oh yeah
maybe we could use like a ring magnet
yes like we used with the pencil right
and and we're gonna need stronger
magnets we're gonna need stronger
magnets are the ring magnets strong yes
they can be awesome all right let's do
it all right
now it's time for a science max quiz
which one of these things do we have
magnetism to thank for
birds flying south in the winter
music or a sandwich
if you picked a
you're right
some birds migrate in the spring and
fall using the earth's magnetic field
many animals can sense the earth's
magnetic field and use it to navigate
migrating birds fly hundreds or
thousands of kilometers north or south
when they migrate in the spring and fall
a compass works the same way by using
magnetism to point to the earth's
magnetic north pole but if you picked b
music
you're right
here's some music
the way you're hearing this music is
because the musicians recorded their
instruments using microphones
use magnets and then the signal was
translated by a computer and stored on
its hard drive which uses
magnets then it was broadcast to your tv
and comes out your speakers which use
you guessed it
magnets
and for those of you who said you have
magnetism to thank for your sandwich
well you're right
you see you'd probably go to the kitchen
to make that sandwich right
well i'm guessing you got all of the
tasty ingredients from your refrigerator
well it works on electricity which is
produced by magnets
and then there's an electric motor in
the fridge that circulates the air and
keeps it cool and guess what magnets and
finally the door on your fridge stays
closed because the door has magnets
so there you go you can thank magnetism
for birds flying south music and your
sandwich it just goes to show when
you're talking about magnets everybody
wins because magnets are everywhere this
has been a science max quiz
[Music]
here's an experiment you can do with a
bag of water take a sharpened pencil and
carefully
push it through the bag
if you do it carefully it won't spill
the reason this works is because the bag
is made of polymers long stretchy chains
of molecules and also because the
pressure of the water against the pencil
prevents any water from spilling out
now
we're gonna max it out
this is a very large bag of water and
here i have some very large
pencils you ready
that's one
that's two
here we go
should i go from the bottom
[Music]
tada
science
[Music]
okay okay okay
i know what you want
like i was saying
science
turns out trying to balance two
repelling magnets on top of each other
is pretty much impossible here's why
this is a magnet and here is the
magnetic field it's often drawn with
lines like this but actually the
magnetic field radiates out in all
directions really think of the magnetic
field kind of like a ball
when you try to balance another magnet
on top of the first magnet it's about as
hard as balancing one ball on top of
another ball so here's the plan just
like the levitating pencil we're going
to use ring magnets because we can put a
shaft through the center of one ring
then drop another ring magnet on the
shaft it will keep them perfectly
aligned then it's just a matter of
putting the bottom magnet on a board to
keep it stable and using another board
so i can stand on it and ta-dah magnetic
levitation or at least that's the plan
okay
board magnets magnets
look at that awesome and now i'm gonna
put the platform on
nice i got some weights here let's see
how this works
yeah
this is gonna work amazing all right i
think i should try it give it a try okay
here we go
huh
yeah i'm doing it i'm levitating
what just a little bit
oh really yeah so hmm
yeah what do we do we need more power
more power i like that idea how do we
give it more power uh
more shafts more magnets
okay sure well why don't we do um when
we do one two three four shafts and then
we'll have magnets on all the shafts
great idea all right
let's do it
[Music]
if you attach something ferromagnetic
like this washer to a magnet
not only does it stick but the magnetic
field travels down the metal
making it a magnet too which means you
can stick more and more things
to each other
and they will continue to stick
until
you run out of magnetic field you can do
this yourself at home with anything
ferromagnetic paper clips work pretty
well or washers like i have or screws or
bolts and they'll continue to stick to
each other as long as the magnetic field
is strong enough you can see it's
getting pretty weak here and they'll all
stay magnetized as long as the first one
is still attached
to the magnet
but if you want to go even further all
you need to do is keep adding more
magnets to reinforce the magnetic field
i've got a few
here
like this let's get the chain started
like that and then i've got a magnet
attached to this washer
so it will keep the magnetic field
strong
and i continue to add
one magnet one washer and we'll just see
how far i can go
[Music]
you can even
sculpt it a little bit look at that and
then at the end
a whole bunch of paper clips
eventually the weight will make it fall
off but it's a lot of fun to play with
magnets and make art
speaking of art you can make with
magnets you can also make sculptures
when everything sticks to everything
else you can make some pretty fancy
designs this is a rare earth magnet a
very strong one and a bunch of nuts that
i've gotten and this one here is an
electromagnet but electromagnets are a
little different because they need an
electric current to work
check this out this is sort of a
magnet dude with crazy hair there's an
earth magnet here and this is a giant
screw and these are some metal bits and
then i've got two more magnets at the
top here to hold on his crazy wire hair
he's got crazy wire hair because he's
crazy magnitude now of course we
couldn't just talk about magnetic
sculptures without maxing it out so
let's max it out
this is a bunch of scrap metal from
leftover experiments and i've got a
bunch of rare earth magnets and now i'm
gonna max out a magnet sculpture
[Music]
[Music]
there you go a maxed out magnet me
i made this guy out of metal pipes with
earth magnets in between and these are
his arms attached of course with magnets
his hand is little metal pieces attached
with magnet steel wool for the hair and
of course hat non-magnetic all right
here we go ready
[Music]
wanna see a magic trick simple copper
tube drop things through it
[Music]
nothing unusual happens but watch when i
drop a magnet through
what
it's not magic it's science because the
magnet creates a magnetic field when it
goes through the tube the magnetic field
repels the magnet upwards now the field
isn't perfect so the magnet doesn't come
to a stop but still it slows down from a
fall to a nice graceful drop take a look
from above
pretty amazing right magnets not magic
science
so i've managed to levitate on some
magnets but just barely what matt and i
needed was more power so instead of
having one shaft and one pair of ring
magnets we're going to use a larger
board and put a shaft on each corner
then we'll have four times the power
because we're using four times the
magnets hopefully this will be strong
enough to get me floating on a cushion
of magnetic energy
and magnets magnets okay here we go
this is gonna work great and
top board
[Music]
oh what do you think looks great yeah
okay here we go
matt
you're limitating i'm levitating
all right it feels cool it's sort of
like it sort of feels like surfing a
little bit all right thank you so much
matt that was amazing and there you have
it science max experiments at large
magnetic levitation you know i'm
surprised we could do an entire episode
on magnets and we never actually got
them so close to the camera that the
camera went all weird because cameron's
and magnets they don't oh dear oh oh
um
no that's okay i can i can
i can fix this if i just maybe no
maybe if i put the magnet to the camera
again that would oh oh okay that's not
that didn't help
oh okay well thanks very much for
watching uh science max experiments at
large and uh we'll see you again as soon
as we you get a new camera
today we're gonna be looking at the
power of magnets magnets
like this
okay this one here is called a neodymium
magnet or a rare earth
magnet it sticks to this
ramona
