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, ...

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.

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.

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 ...

They did this by constructing a chip-based magnetic trap from wires made of niobium, which becomes a superconductor at low temperatures. This trap creates the magnetic field “landscape” needed to ...
