Magnetic dipoles line up. 21 May 2013 Dipole chains – straight lines or zigzags? Photon emission electron micrograph of the magnetic state of the islands at 140 K. In the blue-coloured islands, the ...

Axial dipole magnitude since 1840 (inset, red line, units: nT) and its rate of decay (red shaded area shows one standard deviation uncertainties, units: nT yr −1), from the COV-OBS 6 geomagnetic ...

Every so often, Earth's magnetic field flips on its head, turning the magnetic North Pole into the South Pole and vice versa. It last happened 780,000 years ago, and is predicted to occur again in ...

Also, both electric and magnetic dipole–dipole interactions have been used to create either one-dimensional chain structures or two-dimensional arrays when attractive or repulsive interactions ...
