A new connection between electricity and magnetism

Abstract

Physics 2, 11 (2009) DOI: 10.1103/Physics.2.11 A new connection between electricity and magnetism Robert McMichael and Mark Stiles Center for Nanoscale Science and Technology, National Institute of Standards and Technology, Gaithersburg, MD 20899-6202 Published February 9, 2009 A magnetic domain wall moving along a ferromagnetic wire can generate a voltage across the wire. This electromotive force, which is not the same as Faraday’s law of induction, is part of a growing family of interactions that are being discovered in the field of spintronics.
