Scientists launched a rocket from Svalbard, Norway, that measured Earth’s ambipolar electric field for the first time. The weak field may control the shape and evolution of the upper atmosphere ...

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 ...

As you may recall from Physics 101, a changing magnetic field (like when you slide a bar magnet through a copper coil) induces an electric current. At planetary scale, Earth’s magnetic field induces ...

Researchers from Los Alamos National Laboratory have discovered that cosmic-ray showers seem to play a pivotal role in ...

NASA’s upcoming EZIE mission will use three small satellites to study electrojets — powerful electrical currents in the upper atmosphere linked to auroras. These mysterious currents influence ...

Researchers from Tsinghua University, the Beijing Institute of Technology, the University of Wollongong (Australia), and the Hefei Institutes of Physical Science of the Chinese Academy of Sciences ...

At a cost not far above £10 ($13.70), this was an impulse purchase driven by curiosity; these devices claim to measure both magnetic and electric fields, but what do they really measure?

An invisible, weak energy field wrapped around our planet Earth has finally been detected and measured. It's called the ...
