These lava rope like structures known as pāhoehoe (pahoehoe) are from volcano's.
Could lava sometimes naturally create an electromagnetic coil and/or step up or step down transformers and other energy mutation mechanics?
The magnetic field lines of a current-carrying loop of wire pass through the center of the loop, concentrating the field there

Natural electromagnetic coils and transformers?
Could these be a natural shape for magma wires, similar to how we twist electrical wires such as copper?
Or are they just natural shapes.
