I don't recall the name for it. It's an iron deposit that's also at the location where the pull from the iron at the core of Earth is strongest. There's also a lot more to magnetic north than just where the iron is located. The explanations have phrases like: "flux lobe elongation", "non antipodal attraction", "magnetic dip poles", etc. I don't understand it all myself, and didn't think it belonged in a video for beginners.
@@AdventuresInReach thanks for the reply. Do all compasses point to this all over the earth? I'm aware of magnetic declination and I'm aware of why they say it's there but I used to believe that compasses were a reliable device for people the world over to use to point to the same thing, magnetic north but it doesn't seem to be true. Do all compasses point to the same thing? If they don't really, how do we know what they are really actually doing? They could be pointing to literally anything and nothing at the same time? Secondly, what's the actual evidence for iron at earth's core? In the Kola Super Deep Borehole in North West Russia, they didn't get iron deposits in their samples. They famously found "boiling hydrogen mud", not considered to possibly exist down there and also numerous other false facts they found out. They found out that there was water much much deeper than expected, they found out that bacteria was also much much deeper than expected and that density decreased when they expected a significant increase. Given the above predictions were based on seismology, I believe the only evidence of the iron core is from seismology....is there anything beyond that you are aware of?
My understanding is that as a general rule compasses all point to the same place, with some local variations and some slow changes over time. There are some places like near where i live that have iron deposits that can effect them. I would absolutely rely on a compass 99% of the time while using some common sense and situational awareness. Questioning if a compass is correct will more often than not lead you astray. As for the evidence about the Earth's core, I'm not informed enough to comment.
@@AdventuresInReach thanks again for your reply. I agree with you, I think the compass DOES give us a universal direction, even if it moves slowly over time. Now I'm I'm stood next to an iron ship, yea this might influence it but generally, I do think we all look at the same thing with a compass...but have you seen the declination adjustment of Cape Town, South Africa compared to Auckland in New Zealand? It's 35°!!! This doesn't make any sense to me and I don't believe there could be so much difference. 1 or 2° perhaps but not 35°. I can't explain that but I don't accept it's true in real life. Have a look at Cape Town and Auckland for me....what's going on there? Any reasons/ideas for so much difference?
Those two locations are incredibly far apart. That declination makes sense to me. It's 1 degree in Minnesota US, and it's 10 in Utah where I used to work. That's not even half way across the US--nevermind almost half way around the globe. Magnetic attraction for navigation also is not linear. Look up a declination map of the world. I can't explain it all, but it works.

Awesome and simple explanation! Okham would be proud!
Thank you. I try to keep things simple.
The iron deposit that's located between Canada and Russia? What iron deposit? Has this got a name?
