Compass 1

[vaibhavfromindia]

If you have that magnet. You haven't done anything accept you bought it

[oskay]

@vaibhavfromindia There are two parts to a compass: a magnet and a bearing. For a strong enough disc magnet, I'm showing in this video that you can use the magnet itself as the bearing.

That's a neat trick. If you can't see that, you're not paying attention.

[PokemonTrainerCaseyR]

Well where do you get those kind of magnets?

[SloRollah]

You need to know the poles of the magnet

[AudunBarsk]

just use a real compass to calibrate it

[RonTheelen472]

@SloRollah no you don't need them, you need to know where north is.

[Verradonairun]

how do you know which of the 2 outcomes is north? why couldn't the one you labled as north be south?

[flirtybirdy69]

not as stupid as ur vid..

jackass

[flirtybirdy69]

you hav a magnet under ur shoe dont you?? thats why its pointing at ur direction

[cocopops149]

that was a stupid comment

[2BSilveR]

some how i dont think using a square tub and a square board is the smartest thing in the world.

[imagirly1234]

i can tell time and direction by reading the sun

it comes in handy

its not like people carry around buckets

of water and neodymium magnets

with them...:-P

but good video anyway :-)

[Verradonairun]

I can too, but what if I asked you which way is north or what time it is at night?

not that handy anymore, ain't it. :)

[imagirly1234]

you would have to memorize the way while the sun is up :)

[Verradonairun]

I guess you're right....sorry...^_^

[imagirly1234]

its ok XD

[lighteelco]

your neodymium magnet will rust if you keep it in the water.

[lolerdelol]

yeah really easy all you need is a neadinium magnet...

[noneactive]

And how do you know which way actually is north without checking real compass

[lolerdelol]

maybe check the position of the sun?

[OrangeD00D]

You can use the North Star Polaris at night. Look for the little dipper (Ursa Minor) and it should be at it's tail.

[carrotsRfun]

men have better sence of direction because we have more iron in our nose... :)

[lostfanjay]

cool

[sagsteriscool]

how do you know which way is north and south if its double sided?

[Arrroza]

you have to know which way is north one time to make it...lol, then you just have to label it.

[rickkil2]

@arrroza

how knows the first guy that makes a compass that?:|

[Arrroza]

he has a real one :P

[Arrroza]

oh you mean the first guy that made a compass? then here is the answer:

Sun sets in the east

[loofasfrommars]

yeah, we just made up the directions, so who cares?

[PianoKwanMan]

i use a needle and some toilet paper

[SamJ367]

my grandad did that but i think it involved a nail... cant remember lol!

[meatflavour3]

do all magnets do this when you put them on thier side?

[jonaslovercrazy]

omg!!! that's really cool.. thx!!! helped me with my science project!!!

[KnoxsKorner1]

i do! i have a very bad sense of direction. If i knew which way was north, then i wouldn't need a compass. lol

[onehunglow88]

i do! i have a very bad sense of direction. If i knew which way was north, then i wouldn't need a compass. lol

[onehunglow88]

how do you kow which way is north?

[oskay]

>how do you kow which way is north?

Sounds like you really do need a compass!

[onehunglow88]

i do! i have a very bad sense of direction. If i knew which way was north, then i wouldn't need a compass. lol

[SDial29]

look up... the big yellow fire ball should give you an idea...

[onehunglow88]

i do! i have a very bad sense of direction. If i knew which way was north, then i wouldn't need a compass. lol

[impossible6450966]

@oskay LOL

[TheGyroid]

@oskay

derp he means by how do you know whitch way is north because you dont know whitch side when you label it

[oskay]

@TheGyroid This is *making* a compass. One end points north, one end points south. Physics does that for us. To label it, you need to already know which way is which. The labels-- that is, which end of the earth we call north and south --are given by humans. Physics does not provide a way to tell north from south-- those are just names given by humans.

[mehdi350z]

Very easy! Very cool! and one day this can help you!

thanck you

[ilovemyman001]

I have a compass report and this helped a lot

[PivotyPivoty]

nice

[BenDaHen123]

i like it when you hit the bucket and the waves look weird

[aleks681]

ooo i was gona comment about that too  O.O

[ewlon]

the only good video is when you hit the bucket and you see the waves xD

[GameSharkGuy]

cool

[xiangliang2]

How U Know Which Is North?!

[HazreihelUchiha]

you have a 50/50% guess, now adays you can use a bit commen sense to figure out which way the sun is moving. since its moves only one way.

[themags]

if the sun rises on your right and sets on your left, you are facing north. then vice versa.

[Matthewwong1994]

i have done same thing at Primary school year 1...

[vonhatenfeld]

But the trully magnetic pole in the told South, in fact our world map is upside down!!!!!!

[Adkit2]

it's not upside down, we're the ones who decide which side is up. x.x

[vonhatenfeld]

Of course, agreed!!! But most people think that the magnetic pole is in the told North and it´s not, it´s in the south, that´s what I wanted to clarify. If it´s a rule for the magnetic pole be in the North so our worldmap is upside down!

[Adkit2]

it's not a rule for the magnetic north pole to be north actually. it's the geographic north pole that's always in the north. the geographic north pole (or whatever it's name is) is not in the same place as the magnetic north pole actually.

[vonhatenfeld]

So why did we decide like that? ...probably because the roman empire wanted to be "on the top" of the world because it means superiority!!! And then they started doing like that.

[Adkit2]

or maybe you've got an inferiority complex and the real reason is that it looks the best the way it is. or heck, it might be a completely random thing.

[theDyrectawr]

the replys freak me out!

[Slavkody]

Considering that there is evidence that the magnetic poles switch every few billion years, at some point the "north pole" really was magnetic north.

[themags]

whichever hemisphere you are, the magnet points towards the pole with the stronger pull.

[drewe51]

wow... thats so wrong. Like poles don't ever attract. Most 3rd graders know that.

[oreo4president]

yeah i knew that and im in my mom's BELLY!

[Coastergeekperson04]

Oh yeah, then which body part are you in?

[themags]

that's if you point two magnets together. The north and south pole are named as such just because of their position. Most people who actually have degrees know that.

[drewe51]

are you saying that the north and south poles don't distinguish themselves into a magnetic dipole? I doubt that you have a degree in anything btw. Thanks for the inaccurate input tho. :)

[themags]

I'm saying the magnet's can't distinguish which pole has more pull than the other. Labeling a magnet "North" or "South" doesn't make it intelligent to figure out which side points to where.

[themags]

here's a better explanation. Opposites attract... we can agree with that (North to south, south to north). If the north pole of a magnet is pointing to the North Pole... THEN shouldn't the North Pole be the South Pole? For consistency and to avoid confusion, our magnets are labeled in reverse.

700,000 years ago, the North Pole was the north pole. It abruptly switched poles and scientists can't explain it.

[drewe51]

yeah, I knew that, but that was way before anybody used a compass, i thought you were saying something that you weren't aparently. You realize we're the only people still looking at this clip. haha

and yeah, you just label it north on a compas because it points roughly towards geographic north.

[oreo4president]

yeah i knew that and im in my mom's BELLY!

although i wish she would stop eating..its getting full in here :(

[TheRocketman9]

O_o

[mishypoo]

Hah, 0:04-0:05 is cool.

[Grespano]

It's better to rub one point of a needle with a magnet. It will aways point North.

[JmanRBS]

I actually learn something from your videos..unlike 99.9% of others videos..or watching the tv, My IQ does not go down when watching you.

[HectorDST]

how did you know that that side of the tray was truly north and not south

[oskay]

This is making a compass and labeling its sides, not using the compass to figure out which way is which-- you need to already know which way is north and south.

In this case, I happened to know that I live in the northern hemisphere and the sun was out at mid-day, meaning that if I'm facing the sun, I'm facing south.

[HectorDST]

yea i see.. nice vid

[marcelocent]

Nice Dude!!!!:;)

Cool 5 StaRs

[miharu320]

Nice video

[Tiber1990]

Cool!

[andreewww]

No responds? bah.. sweet Compass.

SUPER EASY!
