Thousands of years ago, Earth’s magnetic field underwent a significant power surge over a part of the planet that included the ancient kingdom of Mesopotamia. People at the time probably never ...

The intensity of Earth’s magnetic field is known to fluctuate over time, and crystals preserved in rock contain tiny magnetic particles that lock in a record of the intensity of Earth’s ...

For the first time ever, clear images of the sun's south pole have been captured by the Solar Orbiter spacecraft. They offer fresh insights into the sun's behavior, its magnetic field and how it ...

The record sheds light on the climate early humans experienced when they were spreading out of Africa. A tree-ringed African lake has yielded a record of Earth's magnetic field spanning the past ...

The third and final result, based on the last three years of data, is in perfect agreement with the experiment’s previous ...

Related: Why do magnets have north and south poles? To investigate Earth's magnetic field — which waxes, wanes and even flips over time — the researchers looked at grains of the mineral iron ...

These small-scale deviations in the magnetic field can actually lead to changes in the large-scale field over time and potentially even a complete reversal of the polarity of the dipole field ...

The output of an alternator can be represented on a voltage–time graph, with potential difference ... parallel to the direction of the magnetic field, so no potential difference is induced.
