Scientists Discover Strange Tiny Signals Coming From Earth’s Core

The Earth's magnetic field is caused by charged particles getting trapped in a dance of currents deep below the surface.

There may be method to the madness according to a new study.

A team led by Nicolas Gillet from the Grenoble Alpes University in France discovered that the planet's magnetic field fluctuates like clockwork every seven years, drifting west at 900 mph around the equator.

Gillet told New Scientist that the magnetic field in the core is important to know.

Scientists have predicted that a thin layer of rock could be causing shifts in the magnetic field between the Earth's outer core and mantle. Gillet's research suggests that the changes could be taking place without the rock layer.

The team analyzed the data from 1999 to 2021. The findings could have a big impact on how we understand the formation of our planet.

Gillet told Newsweek that they try to understand the physics that is responsible for the observed evolution of the magnetic field.

Since their discovery in the late 1970s in ground-based records, these interannual changes have remained unexplained.

Magnetic waves have been found in the core of Earth.

Scientists are puzzled by two huge Masses inside the Earth.
