9.	Concerning the Second or Magnetic Element of the world; that is, concerning the next elementary particle composed of Third Finites Finite: In Swedenborg’s system, a substance with defined limits. 'Third Finites' are complex particles formed from simpler ones. and of the Actives Active: A particle in constant, rapid motion that acts as a force within a system. of the Second and First Finite. Regarding its motion, shape, attributes, and modes. That this element, together with the former one, forms the solar vortex A 'vortex' in Cartesian physics is a whirlpool-like motion of fluid ether that carries planets around a center., and is the primary contributor to magnetic phenomena. . . . . . . . . . . .	195
