Study finds Earth’s magnetic field ‘simpler than we thought’
Earth’s magnetic simpler than we thought
2017/7/24
Scientists have identified patterns in the Earth’s magnetic field that evolve on the order of 1,000 years, providing new insight into how the field works and adding a measure of predictability to chan...
Analysis of a Permo-Triassic polarity transition in different absolute reconstructions of Pangaea,considering a model with features of the present Earth magnetic field
Permo-Triassic Pangaea absolute reconstruction Earth magnetic field polarity transition
2015/9/2
The main objective of this paper is to show that the distribution of transitional palaeomagnetic data recorded at 250 Ma are in agreement with simulated data that depend on the sampling site, using a ...
Earth's magnetic field older than we thought（图）
Earth's magnetic field the planet's core the ancient field
2010/3/26
Earth's magnetic field, which shields us from the Sun's deadly rays, emerged from the planet's core even earlier in Earth's history than we previously thought. While this field, 3.45 billion years ago...
