Imagine waking up one morning to a world where compasses point south instead of north, where auroras shimmer across the ...

Who knew that magnetic fields could be so useful? Astronomers are able to use magnetic fields to map our environment within ...

Imagine crossing vast oceans, soaring across continents, or tunneling deep beneath the earth—without ever getting lost. For ...

Earth's Northern Lights typically dance near the poles, but 41,000 years ago, they lit up skies over North Africa and ...

How a Generator Works When an electric current flows through a wire, it generates a three-dimensional magnetic force field around the wire, similar to that surrounding a bar magnet. Magnets are ...

This heat drives convection cells within the liquid core, which keeps the liquid metal moving through the magnetic field. The so-called Coriolis force also plays a role in sustaining the ...

Gravitational forces that make things fall down to the ground – unless another force stops them. An apple falling from a tree falls straight down. A ball thrown up, comes back down. And so do we ...
