Vertical? The Earth's Magnetic Field?!?!

Does a compass tell us the direction of the magnetic field? How strong is the field when measured in three dimensions? Let's look into it...

First you would need to know how quickly the poles move, then you would need to calculate the differencial of the flux in one random spot on the surface of the earth, i think i have a formula somewhere in my notes. Then you would need to find the time it takes for it to change 0.0002-3 mT wich seems to be the precision of the instrument considering the noise. Oof too much free time needed Edit: B(r)= (,u0/4pi) { [3r*(m*r)/r^5] - [m/r³] } m is magnetic momentum, investigating further... Nvm i can't find m of the earth anywhere and I'm not sure it will work becouse it implies that the radius r is much larger than the lenght l of the dipole, and in our case it's just half of it.

This is a region of iron alloys extending to about 3400 km (the radius of the Earth is 6370 km). It is divided into a solid inner core, with a radius of 1220 km, and a liquid outer core."

Suspend that from a doorway with a bit of tape, and the composite "bar" magnet will always find an orientation to magnetic north, including the vertical tilt.

This is why the south end of a compass needle is counterbalanced, heavier than the north side of the needle so that the north end of the needle is not pulled downwards too much, preventing the compass from being able to move freely. The opposite is needed for a compass to work in the Southern Hemisphere. Just a day or two ago I was responding to a flat earther who said that compasses prove the Earth is flat. He knew about the near vertical magnetic field and I did not so I educated myself on how and why compasses work on a globe. That is when I learned about the counterweighted compass needle. I have learned so much from arguing against flat earth conspiracy theorists. As frustrating as it can be, I have learned more about our planet, space, gravity, momentum, scale, astronomy, reasoning, logic and more in just one year of debating them than I ever learned in my 40 years preceding. Finally I realise that flat Earthers are good for something! Your video on Earth's magnetic field being uploaded today is a nice little synchronicity too!

You wanna tell me that flat-earthers actually use a single-plane compass to prove their hypothesis? While I wouldn't be surprised to hear "yes, really", it doesn't prove anything on the planet's shape - and neither does this video. It just gives a clue, and even if one would took such measurements all around the the world on different latitudes, it still could be "explained" in various fantastic ways. That's what actual science is for - to cut down the number of such explanations by making various tests and calculations. In the end of such process we should stay with only one answer holding true to all of such experiments.

There are rod-shaped bacteria which build a little chain of magnets inside themselves. The magnets give them mostly a up-down orientation, so they can efficiently find the sweet-spot oxygen concentration in the sediment/mud they live in. That's useful for them because they are can only survive over a pretty narrow range of oxygen concentrations (too little means no respiration, but too much is toxic). Anyways, yeah... Unless you're at near the equator, the Earth's magnetic field is mostly up-down. PS: Nice way to do an advertisement. I want one of those teslameters now ;)

[@InssiAjaton]

You follow in the footsteps of the old vikings and your famous countryman Oersted... The vikings are assumed to have sailed in the open seas using an early magnetic compass. Oersted put the science into the magnet business. Great visualizations! Here is a little memory from my childhood. I had a book, called something like “Young Inventors’ and Experimenters’ Book” that described how some boys showed each other their experiments and built items. Among those experiments was how to magnetize steel rods or needles. Then to verify that indeed it had become magnetized, the bigger rods could be hung from their center point to a thin sewing thread and it would turn to roughly North/South. Careful about the twist of the thread, though. But the smaller needles could be covered with a thin layer of butter and settled carefully on top of a full water barrel, where the surface tension kept it floating and it turned freely to N/S orientation. Guess what - I got one of my mother’s sewing needles and repeated the test. That served to teach me about surface tension in addition to the magnetism. And I can be proud that I also did NOT lose the needle.

Hi, I have a few questions. Firstly, I am not advocating for Flat Earth, Helicentric, Geocentric, Concave Earth, Convex Earth, Inner Earth, Infinte Plane, etc etc. I was watching a video, Professor Eric Laithwaite: Magnetic River 1975, and it spiked my interest in magnets. So if my questions seem basic or nonsensical it is because I know very little about them. 1. How is _"a compassed balanced in a way that makes it useful for horizontal navigation"_ ? 2. How does a compass and a dip circle differ, in relation to operation? 3. When you set up the F71 probe, did you also put a compass next to it to compare them for both for North? 4. _"It is believed that the molten iron and nickel in the outer part of the Earth's core is generating the magnetic field"_ This raises many questions, but I will ask just one. Are able to demonstrate or explain how this works, especially in relation to the Curie Temperature? 5. Or maybe two questions - if the molten core is sworling and moving and being affect by the "Coriolis effect" of the earths motion, why does it not produce smaller, more localised magentic fields instead of just one large one? As is demonstrated by the weather. 6. Isnt using a large magnet in the half globe model just a confirmation bias? 7. Did you try the compass on the "southern" half of the globe model? 8. Do you know someone in the Southern hemisphere that can do the same test? Or do you know of a video similar to this one that is performed in the South? Thanks in advance.

[@dylanbiddle123]

1. Since the field points downwards at an angle if you're not on the equator, it will tend to pull one side of the needle down more than the other. The compass needle would tend to tilt if it's not balanced to counteract that unequal force. 2. Since compasses are balanced to keep them level when they are horizontal, the heavy side will pull that end of the needle straight down if held vertically because of gravity. A dip circle is evenly balanced, so it will point at the angle of the magnetic field. 3. No need to do them side by side, compasses and the F71 probe both work, thus they will give consistent results. 4. The center of the earth is solid, even though it's hot because of the immense pressure. I don't know for sure, but i would guess that the curie temperature varies based on the pressure as well as temperature. 5. The core of the earth is solid, thus no swirling. If it was not solid, then there would be no magnetic field. 6. No, it's a model to demonstrate the principle. 7. No need, the compass needle would start pulling the other side of the compass needle toward the magnet as you move toward the south pole. 8. You could go check the governments chart of the main field inclination to get data from points all over the world.

Ray Kent Actually "soon" means tomorrow or within a few hundred thousand years. That’s because we are over due by 300,000 years plus from their calculations. Just as Yellowstone could go off "soon" they can’t predict when but the patterns suggest we are over due. Some also think it’s happening as we speak with abnormalities, and evidence of a third strong point heading north which could cause the flip. Speculating but there might be more then one magnet at the center of the earth with verifying strength, we don’t know what exactly is there after all.

That is also why marine compasses are gimballed and have large vertical freedom. No flat earthers around people who have seen someone sail off over the horizon when out of sight of land.

From my understanding, all Magnets pull towards a huge Iron deposit under or near Hudson lake. This is why there is a declination constant when converting Magnetic north vs Grid North/True north. This is from what is was being taught to us in the Military and traveling the world. For example, in Germany the declination constant was somewhere over 20 degrees west but in most of the US you would have anything from a 3 to 7 degrees east. I am no scientist but I know what the maps said in different parts of the world and having to convert magnetic to true or magnetic to grid, these are the values we would have to use, found in the Maps Legend.

Are you saying north for all magnets across the entire world is pointing toward Hudson lake only?

[@johnridderhof4505]

@@shines9290 there is a difference between true north, grid north and magnetic north and in most cases all three North's point in a different direction. But yes all magnets/magnetic compasses point towards the same local unless acted upon by other or outside interference

[@shines9290]

@@johnridderhof4505 When using a regular old compass it is not pointing towards the north pole but instead to Hudson lake? I really want to understand this. I will look into the three north's as well. Any information you can give me is much appreciated .

[@johnridderhof4505]

@@shines9290 sara, from my training in the military and my deployments around the globe, the short answer is yes. The declination constant on the east coast of the US has a small value west and the majority of the US has a declination constant of east. So Hudson lake may or may not be the exact location but it's used as the land mark for the average orientee. When hiking with a compass and a map the declination constant is a MUST. Otherwise your grid on your map will roatate without you knowing while the land marks will remain in grid position. And any distance and angle you set for your compass the further you go the further you will be off your target. Even though the north arrow on your map orients everything north. But not magnetic north

[@SnoopyDoofie]

Congratulations. You just discovered how pigeons and other birds navigate. The Sun gives longitude while the vertical magnetic field gives latitude. Inside their brains are round structures containing molecular sized magnetized iron particles that due to gravity sit at the bottom of these cavities. Just like the demo you used at the end where the compass points vertical at the equator and horizontal at the north pole, these iron particles shift position inside the cavity and their polarized location is processed by their brains to give them latitude.

[@Veiss7]

I'm still wondering how molten metal can be magnetic, as you know the higher the temp in most metals the less magnetic it gets. The reason they are magnetic at all is the orientation of the grain structure in them is locked in a certain position. So if the magnetic field were really generated by flowing magma or a spinning core it would be unbelievably unstable and varying if it functioned at all.

[@Desrtfox71]

You are thinking of ferromagnetism. That's a permanent magnet. That's not the only way magnetic fields are created. For instance, a strong current also generates a magnetic field (and vice versa).

[@Veiss7]

@@Desrtfox71 But doesn't electrical resistance also reduce at high temp in metals? so how can induction work?

[@Desrtfox71]

@@Veiss7 You just need a current to provide a magnetic field. Currents actually increase when you have a decrease in impedance/resistance. Here's a little info from Wiki on it: en.wikipedia.org/wiki/Electromagnetism And one other smaller link: www.physics.org/article-questions.asp?id=64 Here's another link, this time to an experiment to replicate the effect in a small model: kzbin.info/www/bejne/qHK8iGykbc5geZY Just to give some other info. This effect is based on the fundamental principles of electromagnetism, and is well known.

@@Desrtfox71 that experiment shows no data just people talking next to a machine... in any case do you have some evidence to show magnetism in flowing magma? The article use math and theories but I haven't seen any data or evidence.

@@Veiss7 The Earth's core is not made up primarily of magma. The core is made up of iron primarily, and then nickel. I trust you don't need me to provide evidence of conductivity in such materials?

I have better things to do than argue with someone who will not do the most basic research to educate themselves.
