'Magnetricity' Observed for First Time
from New Scientist
The magnetic equivalent of electricity, dubbed "magnetricity," has been demonstrated experimentally for the first time. Just as the flow of electrons produces electrical current, individual north and south magnetic poles have been observed to roam freely, generating magnetic "current."
The result could lead to the development of "magnetronics," including nano-scale computer memory.
Magnets normally have two poles, north and south, that are inseparable. Cutting a magnet in half only results in each piece developing its own north and south pole. That is true even if one disassembles a magnet all the way down to its individual atoms, since each behaves as a tiny bar magnet with two poles.

Originally intended for science communicators in the Research Triangle Park region of North Carolina, the audio slideshows are now available to anyone online. New talks are posted periodically during the academic year.
