Dirac's æther in curved spacetime-II: the geometric amplification of the cosmic magnetic induction
We search for an amplification mechanism of the seed cosmic magnetic induction by studying a new version of the Dirac's æther in a curved cosmological background. We find that the variation of the scale factor R(t) with cosmic time brings to the magnetic field the desired effect of amplificatio...

| description | We search for an amplification mechanism of the seed cosmic magnetic induction by studying a new version of the Dirac's æther in a curved cosmological background. We find that the variation of the scale factor R(t) with cosmic time brings to the magnetic field the desired effect of amplification, that we call geometric amplification.<br>Procuramos por um mecanismo de amplificação das sementes do campo de indução magnética cósmico através do estudo de uma nova versão do æ ther de Dirac em uma arena cosmológica curva. Encontramos uma amplificação que ocorre se o fator de escala R(t) varia com o tempo cósmico, acarretando um efeito o qual chamamos de amplificação geométrica do campo magnético. |
