Earth's magnetic field is still "tugging", and now scientists can know why

This is related to the liquid metal inside our planet, which generates a magnetic field.

Scientists are convinced that "jerks", which were first detected in 1978, come from fast streams of hot metal in the core of the Earth.

Researchers from the Institut de Physique du Globe de Paris and the Technical University of Denmark used supercomputers to model the movement of metal in the core.

Models suggest that "jerks" are associated with "sudden outflows of buoyancy" in the core, sudden heat releases in the core.

Researchers say that the find can help us better understand the secrets of the Earth's core.

Researchers write: "The ability to numerically reproduce jerks offers a new way to study the physical properties of the deep interior of the Earth."
