N2 - We are investigating the free components of an electromagnetic current,which we describe as a De Rham current over an arbitrary worldline on anarbitrary spacetime MST . These calculations are an extension of a previousresearch done on dipoles and quadrupoles, in which they are described ina metric-free manner. In this thesis, we consider an adapted coordinatesystem to define the free components of an electromagnetic distributionover an arbitrary worldline and extend the previous work done by goingup to the octupole order of the electromagnetic current expansion. Usingthe symmetries of the components found in the calculations, we derive ageneralized expression for the number of free components of any 2^k-tupole current, which satisfies the equation which leads to conservation of charge, dJ = 0.
