Earth's magnetic field magnitude

Hi, the second paragraph states: The magnitude of Earth's magnetic field at its surface ranges from 25 to 65 μT (0.25 to 0.65 G) [3]

This seems to be outdated or incorrect, as the magnetic magnitude in South Atlantic can be as low as 22μT. Source 1: https://en.wikipedia.org/wiki/South_Atlantic_Anomaly Source 2: http://www.geomag.bgs.ac.uk/education/earthmag.html#_Toc2075549

Perhaps a specialist can review... THX.. Shaberer-en (talk) 13:10, 14 February 2024 (UTC)[reply]

Wikipedia is not a reliable source, and I was not able to find the value 22μT in the second source. Can you point out where it is in the second source? Constant314 (talk) 19:18, 14 February 2024 (UTC)[reply]

Hi Constant314,

Thx for your response, sorry for the delay in replying.

the second source states 22,000 nT (=22μT)

same this one (approx middle):

While this one states 22,500 nT:

THX! Shaberer-en (talk) 10:43, 25 February 2024 (UTC)[reply]

I saw it this time in the bgs ref. Looks good. Make the change if you wish, Constant314 (talk) 15:20, 25 February 2024 (UTC)[reply]

thanx - my first update! Shaberer-en (talk) 13:49, 2 March 2024 (UTC)[reply]

GA concerns

I am concerned that this article no longer meets the good article criteria. Some of my concerns are listed below:

There are uncited statements, including entire paragraphs.
There are many sources listed in "Further reading". These should be considered for inclusion in the article or removed.

Is anyone interested in fixing up this article, or should it go to WP:GAR? Z1720 (talk) 08:31, 7 October 2024 (UTC)[reply]

There are a lot of uncited passages, including entire paragraphs. The sources listed in "Further reading" might be helpful for adding inline citations. Z1720 (talk) 15:28, 14 October 2024 (UTC)[reply]

South pole of Earth's magnetic field

@Chetvorno While I have no fond attachment to my edit, should we even have this wonky factoid in the intro? The existing sentence does not, in my opinion, give information. The label on the dipole is a minor detail, not a significant aspect of the Earth's field, and yet it is hard to explain the issue clearly. Johnjbarton (talk) 23:55, 17 December 2024 (UTC)[reply]
