I’d love to be a scientist. You basically get to buy a lot of stuff, put it together, and then film it, explaining that you’re “generating a magnetic field by spinning liquid sodium metal ...

Geophysicist Daniel Lathrop wants, among other things, to use it to predict when the Earth’s magnetic field will next reverse. ... With the sphere spinning at 45 miles per hour, ...

Earth’s magnetic field is generated by the spinning ball of molten iron at the planet’s center. It performs a variety of important functions, including acting as a shield against solar winds.

Once a planet like Earth starts spinning and generating its own magnetic field, that magnetism tamps down turbulence. The scientists at Grenoble can now study how that happens inside the flowing ...

Like a compass, it actually relies on the Earth’s magnetic field to turn. As long as there’s ample light and a planet beneath our feet, this version of Jupiter should rotate forever.

The gravitational field of a rotating black hole is powerful and strange. It is so powerful that it warps space and time back ...

The magnetic field that protects our planet from solar and galactic radiation, ... he’s got this huge sphere filled with liquid sodium. It’s like an enormous metal ball spinning around.

Only one of these should be Zel’dovich-amplified by the rotating cylinder (the co-rotating component) while the other is only ever absorbed, explains Cromb. “Ideally, we want to switch to a rotating ...

There’s no escaping magnetic fields — they’re all around us. For starters, the Earth itself is like a giant magnet. A spinning ball of liquid iron in our planet’s core generates the vast magnetic ...

Around 1,800 miles beneath your feet lies a giant, blazing-hot ball of metal. It's the innermost part of our planet, Earth's core. It has a profound impact on your life, though none of us can even ...

Earth’s magnetic field is generated by the spinning ball of molten iron at the planet’s center. It performs a variety of important functions, including acting as a shield against solar winds.
