Electromagnetotoroid Structures in Propulsion and Astrophysics

We introduce the concept of electromagnetotoroid in astrophysics and its role in polar jets, showing that it represents the onset of Abraham's force driven by some external source, such for example, gas fall to star center. We have shown in this paper that the Abraham's force term is the analogue of the Magnus force, and thus represents the formation of vortex structures, of electromagnetic nature, in the fabric of space-time. The proposed concept can be transposed for spaceship propulsion. This study points to prove that major processes for propulsion on Earth (e.g., birds, fishes) and in the Universe (e.g., HH objects) have all the same underlying nature, the formation of vortical structures being at their basis.
