Earth's Magnetic Field | Science is Fun🌍🧲✨
Explore how Earth's liquid metal core generates the Geodynamo shield, deflects solar wind & creates auroras! Video by @NSC_Delhi🛡️⚡
What if Earth's magnetic field disappeared? Tell us below!👇

🌍 Earth’s Geodynamo 🧲
Deep inside Earth, moving molten iron generates our planet’s magnetic field. It shields us from much of the solar wind, while guiding charged particles toward the poles—creating the beautiful auroras. 🌌✨

Erdmagnetfeld: Schwächezone weitet sich aus. Anomalie im Südatlantik wächst und vertieft sich – aber warum? #Erdmagnetfeld #Magnetfeld #Südatlantik #Magnetanomalie #Geowissen #Geodynamo

Wann entstand das schützende Magnetfeld unseres Planeten – und wie stark war es? Eine überraschende Antwort liefern nun 3,7 Milliarden Jahre alte Gesteine aus Grönland. #Erdmagnetfeld #Magnetfeld #Erdgeschichte #Geologie #Geodynamo

So excited to have @MinSoc_UK speaker @TinySpaceMagnet giving the ESSRG seminar at @UofGGES & @UofGlasgow 🤩 Can’t wait to hear all about the ancient (3.6 GA old) #geodynamo & what this means for plate tectonics & planetary #habitability 🤩🧲🌍

.@ericgmeyer explains why without nuclear power-- none of us would even be around to talk about it!

[#Séminaire #IRPHE] le 10/02 à 11h : « The Role of Inertial #Waves in the #Geodynamo ». Peter Davidson / @Cambridge_Uni will explain how #numerical #simulations of the geodynamo are beginning to approach a #dynamically relevant regime.

Le noyau terrestre est parcouru par des ondes rapides très spéciales https://t.co/JZSSFDVsHO #geodynamo
Earth’s magnetic field is generated by fluid motions (geodynamo) in the outer core, which has operated for >3.4 Ga 🌍
Maylis Landeau et al. review the mechanisms proposed to sustain the #geodynamo for >75% of Earth’s history

Kyle Gwirtz of @uarizona presents a reduced-order #model of the #geodynamo that assesses #data assimilation systems for #geomagnetic forecasting at #SIAMMPE20. https://t.co/sdbBioXE06
Researchers improved the estimate of the age of Earth's solid inner core, putting it at 1 B to 1.3 B years old.
Furthermore, the study helps pin down the magnitude of how the core conducts heat, & the energy sources that power the #Earth's #geodynamo.

Doppeltes Rätsel ums Erdmagnetfeld. Neue Schwächezone im Süden und "tauziehende" Strömungen im Norden. #Magnetfeld #Nordpol #Geodynamo https://t.co/ZMrY7kfZ86
New paper out investigating the start of #Earth's #geodynamo. #paleomagnetic, #geochemical and #mineralogy studies conclude that the geodynamo before 3.5 Ga ago remains unknown. Paper by @caueborlina et al: https://t.co/r5nlBceRu5
Happy to share this paper on Earth’s magnetic field history! A lot of work @eapsMIT, learning and collaboration involved. We show that the early evolution of the Earth’s magnetic field is yet to be determined https://t.co/aw6iCbwQqj
Prehistoric minerals suggest Earth’s strong magnetic field was in place 4 billion years ago, likely powered by an internal #geodynamo. In PNAS: https://t.co/l2fiz5CP7h
Ur-Magnetfeld ohne Erdkern? Schon vor 4,2 Milliarden Jahren besaß die Erde ein starkes Magnetfeld. #Magnetfeld #Geodynamo #Erdmagnetfeld #Erdgeschichte https://t.co/mb2rHwwqaw
Excited about our new paper published in GRL: "Geodynamo Conductivity Limits" !!!
https://t.co/G9c0JdCFhS
Ever wonder if there are theoretical limits to planetary magnetic field intensity? Or how close Earth is to its "optimal" magnetic state? #geodynamo #AGUpubs
Wonderful development in experimental planetary science. https://t.co/QUHKMSJUtA #science #stem #astronomy #geodynamo
