As the time line at right shows, hundreds of times in our planet's history the polarity of the magnetic shield ensheathing the globe has gone from "normal," our current orientation to the north ...

The shift in polarity marks the point at which the sun is halfway through solar maximum, the height of its activity, and the beginning of the shift toward solar minimum. The sun's magnetic field ...

As there-could be no magic in the case, it appeared that the balance had magnetic polarity, as no other cause could produce the effect I had witnessed, and which was repeated as often as I chose ...

Researchers from the Department of Physics have managed to experimentally develop a new magnetic state: a magneto-ionic ...

The astronomers found that the surface magnetic-field strength of the white dwarf in ZTF J0112+5827 is approximately 38.7 MG, which indicates the system's polar nature. It turned out that there is ...
