When an electric current passes through a metal wire, a magnetic field forms around that wire (see diagram at right). Likewise, a wire passing through a magnetic field creates an electric current ...

Firefly Aerospace's moon-bound spacecraft has provided the closest thing to a reflecting pool in space, showing Earth as an imposing monument, stacked on top of another Earth. The illusion is a ...

Back in 1832, the celebrated British physicist, Michael Faraday, carried out a set of experiments designed to answer a tantalizing question: could electricity be generated by Earth's rotation through ...

Earth’s magnetic north pole is on the move, and scientists are racing to keep up. This week, the release of the World Magnetic Model 2025 (WMM2025) sheds new light on the enigmatic shifts in ...

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 ...

Most of the time, the Earth and Sun’s magnetic fields are misaligned, leaving our planet’s field less open to the ...

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 ...

The World Magnetic Model predicts shifts in Earth's magnetic field using data from satellites like ESA’s Swarm mission. Milk genes Neanderthals? New study reveals a surprising ancestral twist ...

The time period, which spans 770,000 to 126,000 years ago, started with a reversal of the planet’s magnetic field. Kerry served as The Scientist’s news director until 2021. Before joining The ...
