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 ...

Thus, a magnetic dipole - such as a bar magnet - has north and south magnetic poles. ... So, by applying a magnetic field gradient and tailoring the frequency of the wave that “kicks” ...

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

As the dipole field is the source of the toroidal field of the next cycle, its strength should be a measure of the activity of the next cycle. Such a correlation has already been established: “During ...

Every breath we take in contains 21% oxygen, the gas that makes life on Earth possible. Oxygen, in its combined oxide state, ...

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 ...

Plasma Chamber. Scientists have observed how a magnetic dipole field can create what looks like a glowing, localised fireball inside a plasma chamber. By placing a regular dipole bar magnet near ...

Earth’s magnetic field is known to flip direction with a somewhat unnerving regularity: magnetic north switches to south, and vice versa. The processes that drive this change are poorly ...

Earth’s Magnetic Field Could Take Longer to Flip Than Previously Thought New research suggests a polarity reversal of the planet takes about 22,000 years, ... represented as a dipole magnet field.
