Web22 okt. 2024 · In 2012, a team of scientists led by Chou Yumin from Southern University of Science and Technology excavated a one-meter long stalagmite. The record from the sample proved that 98,000 years ago, the magnetic north pole was somewhere in the southern hemisphere. WebThe Earth's magnetism is generated by molten iron and nickel convection currents in the earth's core. Charged particles in these currents generate magnetic fields. The sun also releases ionizing charged particles towards the earth known as solar winds.
WebTherefore, Earth's magnetic field can be described by having two poles, but in reality, it's much more complex. Part of this is due to crustal structure (i.e. the magnetic anomalies we typically work with in geophysics to, say, locate an igneous intrusion or understand the evolution of the oceanic crust).
