Bipolar reversal magnetic theory
WebDec 1, 2009 · The presence of sign reversal of both magnetization and exchange bias field in a single system has potential utility in manufacturing storage devices thermally assisted magnetic random-access ... Webthe magnetic field does not flip sign under time reversal (the electric field does), but the theory is time reversal invariant anyway; it is the classical analog of Feynman’s view. This paper explores the ‘classical Feynman’ view, and issues that it throws up concerning the ontology of electromagnetism and the mean-
