“The external magnetic field of the Moon is very weak in comparison to that of the Earth.” So apparently it has one. Ganymede has a magnetic field.. I couldn’t work out whether Io has a magnetic field, but she interacts very strongly with the magnetic field of Jupiter itself. Anyway, it seems the answer to your question is yes.
