The reversal could actually have a beneficial effect on Earth. The sun is on the verge of a significant event: a magnetic field reversal. The sun undergoes such a reversal every 11 years ...

Abstract: Theoretical values of the magnetic field intensity outside a permanent magnet usually agree with experiment only at distance greater than the length of the magnet. This theoretical formula ...

Our physics expert picks his top-five equations, plus a scheme to supply US power needs with a bucket of baseballs. Thanks, Einstein!

the magnetic north pole’s position is determined by Earth’s magnetic field, which is in constant motion. Over the past few decades, magnetic north’s movement has been unprecedented — it ...

Something strange is happening in Earth’s magnetic field, and it has caught NASA’s attention. A massive region of lower magnetic intensity, known as the South Atlantic Anomaly (SAA), has appeared ...

The study of primordial magnetic fields in the early universe is a fascinating area of research that seeks to understand the origins and implications of magnetic fields that may have formed ...

Instead, magnetic north is the changing location where the planet’s magnetic field lines converge. This field is generated by the churning of the planet’s outer core, a layer of molten iron ...

NASA is worried about the South Atlantic Anomaly (SAA). This anomaly affects Earth's magnetic field, which may pose risks to satellites and the International Space Station. The SAA is caused by ...

NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest ...

NASA is closely monitoring the South Atlantic Anomaly, which is a growing dent in the Earth's magnetic field that allows charged solar particles to approach the surface. A huge 'dent' anomaly in the ...

Electric and magnetic fields are important factors to be considered when designing transmission lines. They occur in nature and have become much more prevalent in our everyday lives through man-made ...
