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.

The scientists utilized magnetic fields to control the shape and movements of the shape-shifting liquid metal robots. The hope is that by using magnets to help move and control the shapeshifting ...

“We find that both exhibit strong linearly increasing trends, coupled with a large surge in magnitude between 330 and 220 ...

One of the most enduring mysteries stemming from the Apollo moon missions is why rocks brought back to Earth for analysis are magnetized. There's no magnetic field on the moon today and scientists ...
