Earth’s magnetic field strength and atmospheric oxygen levels have oscillated in tandem for around 540 million years, according to a NASA-led study, pointing to a deep-Earth process that could knit ...

Earth’s magnetic field has correlated with fluctuations in atmospheric oxygen, according to a newly released study.

Geologic records reveal that magnetic field strength and oxygen levels rise and fall together, implying deep-Earth processes ...

Antennas installed at 18 U.S. high schools detected bursts of radio activity that can precede solar disturbances capable of ...

New NASA research demonstrates that 540 million years of Earth’s magnetic field changes have corresponded to surface ...

Scientists convert Earth's magnetic field collapse from 41,000 years ago into chilling audio, revealing ancient cosmic ...

A rare geological event occurs every 300,000 years or so: the Earth’s magnetic poles flip. The magnetic poles are the two ...

Radiation source structures for board level shield can evaluation are considered, and a new approach to generate a parasitic-less magnetic dipole moment is proposed. The concept uses a slot-backed ...

Scientists in China claimed that the magnetic shield over North America is weakening rapidly. The geomagnetic field, a kind of natural barrier, protects Earth from cosmic radiation, which can ...

It's a gradual transition from a dipole to a complex magnetic field, to a reversed dipole over the entire 11-year solar cycle. "In short, there is no specific 'moment' in which the sun's poles ...

Interestingly, although some IR-active pseudorotations do feature a rotating electric dipole moment, a direct conversion of this motion into a magnetic dipole moment, as suggested by classical ...
