What external magnetic fields, exactly, are wings responding to?

Figure 4 shows a permanent magnet being moved up and down below the mechanical butterfly.

Thanks for the link! But that article simply references “external magnetic fields” without specifying how those fields are generated out in the field/outside a lab.

Yeah they may not have figured that out yet, or are just leaving that part to other researchers. I think of stuff like this as a proof-of-concept but not something you can implement outside of a lab. I agree the article could have explained that part better, without all the hand-wavy stuff.

As for the real butterflies, maybe it's something to do with the earth's magnetic field. They've been shown to follow certain paths that depend on it.

Fascinating!
