Scientists have captured magnetic signatures from Earth's ocean tides in the finest detail yet. These faint signals, which certain satellites can detect when flying at very low orbits, may hold ...

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 ...

The "audio represents the magnetic field generated by Earth's core and a solar storm," according to the European Space Agency (ESA). Credit: Space.com | animations and audio courtesy ESA/Planetary ...

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

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 ...

This, in turn, affects convection in the outer core—the dynamo-like process that generates the magnetic field that protects life on Earth from harmful cosmic rays. "Flow in the outer core drives ...

When the Earth’s magnetic field is strong, as it is today, the amount of carbon generated by this interaction is relatively low, but it spikes when the magnetic field weakens and allows more ...

Earth’s magnetic field is not fixed—it drifts, flips, and even weakens over time, altering navigation and planetary protection from solar radiation. Since its discovery in 1831, magnetic north ...

Magnetotactic bacteria synthesize magnetic iron nanominerals, which function as tiny compasses that allow the microbes to navigate using Earth's geomagnetic field. Earth's iron cycle is a very ...
