Hello Io, From Galileo
FortKnox writes: "This afternoon super-durable Galileo will swoop in on the south pole of Io. Scientists hope to learn a little more about the volcanic moon of Jupiter. And it shows some great NASA innovation in the little probe still working great (although low on fuel). Fly-by will happen at 3:23pm EST."
As i recall, if a body is magnetic (induced or otherwise) it will look the same from the outside. Perhaps that is why they want a close flyby to be able to monitor small changes near the surface.
If anyone knows how you can distinguish between an intrinsic and an induced magnetic field, please step forward and explain.
