In addition to electromagnetic fields, researchers have also focused on gravitational waves, particularly in the context of Bianchi type universes. Two studies explored the geodesic deviation and ...

Earth's magnetic field occasionally bursts into song — but these compositions are written with electromagnetic radiation, not ...

By way of comparison, he noted that neutron stars – the densest objects in the universe – have fields ... explained by the ...

he cut his teeth as a field theorist, learning the then recently developed theory of quantum electrodynamics, which described electrons and their interactions with electromagnetic fields.

But wait – isn’t that a geomagnetic field? Well, yes – but if someone’s told you that makes it a different kind of thing from the electromagnetic field coming out of your cellphone ...

As tides push ocean water around the globe, its interaction with the planet's magnetic field generates a weak electric current. This current in turn produces a weak electromagnetic signal that can ...
