For decades, ferromagnetic materials have driven technologies like magnetic hard drives, magnetic random access memories and ...

Have we finally solved mystery of magnetic moon rocks? Simulations show how effects of asteroid impact could amplify the early Moon's weak magnetic field.

For the study, the researchers used computer models based on data obtained from NASA’s now-retired Mars InSight lander to simulate conditions within the interior of Mars depicting the absence of an ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously ...

The planet's once-strong magnetic field appears to have been limited to its southern hemisphere, the apparent result of a fully liquid inner core that differs from that of Earth ...

The first core update of the 2025 year, the March 2025 core update, is now done rolling out and complete. It started on March 13, 2025 and completed about 14 days later on March 27, 2025.

Researchers studying decades of earthquake data say they have found the first evidence that, in addition to spinning backward, Earth’s inner core in changing shape.

Melexis has announced a magnetism-based current sensor that needs no ferromagnetic core, for measuring currents through power PCBs and busbars (see diagram). MLX91235 is gradiometric, taking a ...

Earth’s inner core is a hot, solid ball—about 20% of Earth’s radius—made of an iron alloy. The planet’s outer core, beneath the rocky mantle, is a colder, liquid metal. Geophysics models explain that, ...

How Magnetic Fields Control Flow Within Earth’s Core Strangely, it seems the planet behaves magnetically as if there was a cylinder at its core, not a sphere.

A doughnut-shaped region thousands of kilometers beneath our feet within Earth's liquid core has been discovered, providing new clues about the dynamics of our planet's magnetic field.
