How Do Compasses Work?

The only thing i learned from this video is that earth is a giant magnet instead of how compasses work

Dude : takes initiative to explain something! Also Dude : sets the background music louder than the dialogue! ☝️👏👏👏

Besides the distracting music in the background, the guy is bascically trying to say: The Earth is a giant magnet, the needle inside the compass is also a magnet. The magnet's north pole naturally aligns with the opposite pole of the Earth's magnetic field at a spot called the magnetic North. Because like-like repel. Hopefully this helps.

All magnet are effected by north poll, but gravity makes it difficult for the magnet. You cannot rotate a car with your hands, but you do that in space. You can not rotate a heavy boat on ground with your hands, but you can rotate a heavy boat with you hands if parked on water. When gravity is somewhat eliminate, then a magnet can rotate in the direction of north poll. In a compass, the needle floats in a liquid that eliminates gravity. That’s how people can use only a needle on top of a tiny leaf, place on water, to find the direction.

The music is really distracting.

Asking again...... How Do Compasses Work????

If same poles repel, how come the north needle of a compass is pointing north? =/

Now I'm confused

The video does not really explain how the compass works, it rather summarizes what a compass does. Dislike.

How can 2D model compass work in the 3D environment aka globe? Just curious...

1:28 -- So you don't know.

How does the magnetic needle detect north and south that far? Is there a magnetic wave from North Pole to the compass if so how does it travel that far?

Does it work better in 1 location vs another? Let's say I take a compass to New York, would the needle spin more forcefully than if I took the same compass to the equator? I've heard if you take it to the North Pole it will just continuously spin. Does it do the same in the South?

Nice Film, BUT the compass works only so long, as the poles doesn't change. Cheers for uploading and sharing. Bye bye Toni

Who invented the compass [amongst many other things]? In case you forgot. \ In Chinese, they are called, 指南針 "needle that points south" Europeans use North as the reference.

Thank you! This helped me with science homework so much ❤😂🎉😊

I wish if Einstein could find this video when he was young

I KNOW ITS A MAGNET BUT HOW. I HAVE A NORMAL MAGNET(U KNO THOSE OVAL RUGBY BALL SHAPE TOY MAGNETS) BUT IT DOESNT ACT LIKE A COMPASS NOR EVEN BIAS A CERTAIN DIRECTION.

Here from physics. You literally explained nothing. It's actually not as simple.

@livescience a little bit of study is needed for this simple tool that doesnt do what it is believed to do. How can it always point to a constantly changing magnetic field yet stay localized in direction? What is actually happening is it is showing the way towards the back of the planets atmosphere, expressing the forces of velocity imposed on it. Thus when you get close to the "back end" or "front end" in correlation with the vector of our descent towards the sun it will spin. The direction in which the tip pitches shows whether you are at the point where matter goes out from the earth or comes in. The in part of where the force of wind enters the earth, can be felt by added pressure on the body and "north" pitched down. On the opposite end, the great teepee and the "north" pitches up or out. Not hard to figure out if you use common sense.
