Just what I was looking for! As an additional bonus, if I'm ever trying to avoid going somewhere I now know I can tell people that the non-uniform declination of earth's magnetic field meant that my compass wasn't pointing me in the right direction.
To confirm, the field created by the iron currents is because it's a moving conductor, correct? Most of what we've done in class has been around the field created by moving charged particles, but can't Iron only be considered a charged particle if its plasma? My chemistry knowledge is, well, lacking, and self-taught; so I try not to confide in it! I assume that this is a case of faraday's law rather than the behavior of charged iron Ions?
Great questions! If you have electrically neutral iron, it seems that this doesn't qualify as moving charge, yet somehow it is, so I'm not exactly sure, but here are some relevant links: en.wikipedia.org/wiki/Dynamo_theory www.eurekalert.org/news-releases/639913 "Scientists know that today the Earth's magnetic field is powered by the solidification of the planet's liquid iron core. The cooling and crystallization of the core stirs up the surrounding liquid iron, creating powerful electric currents that generate a magnetic field stretching far out into space. This magnetic field is known as the geodynamo."
Are you aware of the latest position ? Many miles away since 2015 ! You know that the tree line has been following and that the cold has moved with it ? The winds have changed also. Many other things to.

I was not aware, as I don't follow the movements too closely. Thanks for sharing!
