Fluctuations in dimension fold over on each other.
Folding, undulating Dimensions form a plasma. As the plasma travels, a magnetic field is induced. The magnetic field forms odd, “bubble-like structures” called magnetic islands.
“These may be produced from helical current perturbations in the plasma,” Oak Ridge National Laboratory published in a report from 1974. “Physically the islands are a result of having a harmonic component of the radial component of the perturbed magnetic field in resonance with the unperturbed rational surface field lines, in the presence of shear.”
