It flows just like the liquid metal that surrounds our planet's solid inner core, ... Since its ability to generate magnetic fields is five times stronger than pure liquid metals', ...

When Our Magnetic Field Flips. By Rick Groleau; Posted 11.18.03; NOVA; Every so often—every 250,000 years on average—the Earth's magnetic poles reverse polarity.

In the Earth (see image below right), the liquid metal that makes up the outer core passes through a magnetic field, which causes an electric current to flow within the liquid metal.

Yale researchers create liquid metal that mimics Earth's magnetic core ... It generates magnetic fields up to five times stronger than pure ... Boris reacts to local election results in his Daily ...

The Earth's magnetic field is a result of the movement or convection of liquid iron in the outer core. As the liquid metal in the outer core moves, it generates electric currents, which lead to a ...

Since magnetic particles are sprinkled throughout the gallium, a permanent magnet can drag it around. In solid form, a magnet can move the material at a speed of about 1.5 meters per second.

Within supersized alien versions of Earth, a common transparent ceramic may become a flowing liquid metal, perhaps granting those distant worlds magnetic fields to shield life from harmful ...

The history of magnetism on Mars remains a critical field of study since it is closely tied to the planet’s potential capacity for life billions of years ago. Mars’ magnetic field was once generated ...
