A Look at Pluto's possible Magnetosphere
No one knows whether or not Pluto has a magnetosphere. Scientists were very surprised to find that Jupiter's icy moon Ganymede had a magnetosphere because it is hard to explain how an icy body can develop a magnetic field. Nevertheless, Pluto may well have a magnetic field, as a result of its dual orbit with its moon Charon.
On the other hand, Pluto may have a reaction with the field found between planets that is similar to that of a comet, as illustrated in this diagram. Only exploration of this unique system will give us the answer.
