Simulations prove early Earth's liquid core generated protective magnetic field

Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged particles that make life difficult.

Even A Liquid Earth Core Generates A Magnetic Field

Eddie Gonzales Jr. – MessageToEagle.com – For more than 100 years, scientists puzzled over whether a stable magnetic field was already generated in Earth’s early days—when its core was still completely liquid, unlike today. Now, a team of geophysicists has shown with a simulation that this was very likely. A (simulated) look into the Earth’s […]

A fully liquid Earth’s core also generates a magnetic field

30.07.2025 - For more than 100 years, scientists have puzzled over whether the Earth's magnetic field had already been generated stably back in its early days when its inner core was fully liquid - unlike it is today. A team of geophysicists has used a simulation to show that this was highly likely.
