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- WebDec 15, 2024 · As shown in Fig. 1, the magnetization reversal phenomenon in Ni 20 Mn 3 B 6 alloy is characterized by the M-T curve. The M-T curves at 10 Oe external field is illustrated in Fig. 1 (a). For the ZFC curve, the sample was first cooled from 300 K down to 10 K under zero field, and magnetization data collected at temperature warming from 10 …
