The chances are that there is a magnetic field for Io. Io is composed of lots of iron, Io is warm inside, and Io spins rapidly. These are all the ingredients for a magnetic field. The Galileo spacecraft will take detailed measurements to make a determination of whether there is an Ionian magnetic field or not.

Io's main contribution to Jupiter's magnetosphere is known as the "Io Torus", a donut-shaped cloud of particles which came from the atmosphere and found their way into the the magnetosphere. The cloud forms along the path of Io's orbit. This object has a major influence on Jupiter's magnetosphere.

Io probably has a magnetic field. Io is made of lots of iron, Io is warm inside, and Io spins fast. These are all the ingredients for a magnetic field. The Galileo spacecraft will take many measurements to find out if there is a magnetic field or not.
