Earth’s core is transforming, which could affect the length of our 24-hour day, Earth’s magnetic field, and more ...

We are unsure of the nature of the strange doughnut-shaped structure discovered inside the Earth's core. We thought Earth had ...

Researchers discovered a donut-shaped region at the ceiling of the outer core This lighter region helps stir the liquid metal which generates the magnetic field Scientists have uncovered a vast ...

A newly discovered "doughnut" in Earth's core could influence the planet's magnetic field. In a new study, researchers observed the doughnut-shaped structure for the first time by looking at ...

This generates a poloidal magnetic field that bends the plasma current into a circle (green vertical circle). Bending the column into a circle prevents leakage and doing this inside a doughnut-shaped ...
