The Earth's magnetic field is one of the important factors that maintains the delicate balance we have. In Earth's history, its magnetic field went through a weakened state before solidifying.
In a recent study, researchers are trying to plot out these phases of Earth's magnetic field. Hopefully, this may also help us predict any possible shifts that might happen in the future which could cause catastrophic damage to our world.
