Electromagnetic mass was initially a concept of classical mechanics, denoting as to how much the electromagnetic field, or the self-energy, is contributing to the mass of charged particles. It was first derived by J. J. Thomson in 1881 and was for some time also considered as a dynamical explanation of inertial mass per se. Today, the relation of mass, momentum, velocity, and all forms of energy – including electromagnetic energy – is analyzed on the basis of Albert Einstein's special relativity and mass–energy equivalence. As to the cause of mass of elementary particles, the Higgs mechanism in the framework of the relativistic Standard Model is currently used. However, some problems concerning the electromagnetic mass and self-energy of charged particles are still studied.

dbo:abstract
  • Die elektromagnetische Masse, auch scheinbare Masse oder effektive Masse, ist ein Konzept der klassischen Mechanik bzw. Elektrodynamik. Sie gibt an, inwieweit das elektromagnetische Feld bzw. die Selbstenergie zur Masse eines geladenen Teilchens beiträgt. Die elektromagnetische Masse wurde zuerst von J. J. Thomson 1881 abgeleitet. Zu Beginn des 20. Jahrhunderts wurde die elektromagnetische Masse als Erklärung für den Ursprung der Masse in Betracht gezogen. Diese Interpretation wurde jedoch zu Gunsten der Aussagen der Relativitätstheorie verworfen. Masse, Impuls, Geschwindigkeit und allen möglichen Energiearten hängen durch die Äquivalenz von Masse und Energie miteinander zusammen. Was die Ursache der Masse von Elementarteilchen betrifft, so wird der Higgs-Mechanismus im Rahmen des relativistischen Standardmodells benutzt. Für den Spezialfall der elektromagnetischen Selbstenergie von geladenen Teilchen kann allerdings weiterhin das Vorhandensein einer „effektiven“ elektromagnetischen Masse angenommen werden. (de)
