Earth’s trusty magnetic field has been keeping the planet safe for at least 3.7 billion years. There’s a chance it might have ...

Earth's magnetic field was so weak it almost disappeared. Then, seemingly out of nowhere, complex life emerged.

A tree-ringed African lake has yielded a record of Earth's magnetic field spanning the past 150,000 years. A core of rock and ...

Earth’s magnetic field is generated by a 2,000 km thick outer ... now is a great time to discuss all the ways this simple phenomenon has had profound impacts on our lives and the development ...

"At some point it might not be beneficial anymore to stick around with your buddies. But if you don't, you die." ...

Likewise, a wire passing through a magnetic field creates an electric current within the wire. This is the basic principle that allows electric motors and generators to operate. In the Earth (see ...

Geophysicist Daniel Lathrop wants, among other things, to use it to predict when the Earth’s magnetic field will next reverse. Over the course of our planet’s history, the field has flipped ...

Would a dramatic change in the Earth's magnetic field affect creatures that rely on it during migration? Late on a January night in 1993 I found myself on a beach on the Pacific coast of Costa ...

Creatures from migratory eels and other fish species to insects to birds tap into the Earth’s magnetic field to navigate, sometimes many thousands of miles. But so far, evidence has been scant for any ...

Their approach is to sense anomalies in the Earth’s magnetic field and compare them with a known map of the field to work out their position. And because they use quantum sensors for this process, ...

"We need a way to date these sediments." That's where the variations in Earth's magnetic field come in. When rocks form, they lock in a record of the magnetic field via small magnetic crystals ...
