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” ...

I'll come back to where that initial magnetic field comes from, for now let's just say we start with some weak dipole field. That field passes through the liquid outer core which is an electrical ...

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 ...

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 ...

This dipole field — which defines the Earth’s magnetic poles — has reversed polarity tens of thousand of times in the past. We know this because ancient field configurations are “frozen” into the ...

Every breath we take in contains 21% oxygen, the gas that makes life on Earth possible. Oxygen, in its combined oxide state, has always been abundant in Earth's crust, but elemental diatomic oxygen ...

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.
