Earth magnetic field strength over time
Web1 day ago · Crutcher et al. noted that, on average, three-dimensional magnetic field strength is related to the magnetic field strength in the plane of the sky by B = 4/π × B pos. While it should be noted that this strictly holds only for a statistical ensemble of measurements, the mass-to-flux ratios obtained using this estimate of B are 0.41 ± 0.07 … WebMay 16, 2016 · It shows how the strength of Earth’s magnetic field changed between 1999 and mid-2016. Blue depicts where the field is weak and red shows regions where the field is strong.
