Magnetic fields

    The magnetic fields of several planets in our solar system are from what I've read caused by electric currents - does anyone know what the electric currents are caused by?

    maybe some references would be good for us(me) what you are looking for.

    I think the current is generated inside the planet.

    What I found in a book on our solar system was that Jupiter and the other gas giants were believed to have their magnetic fields caused by electric currents inside the planet. What I was specifically looking for was the cause of these electric currents.

    ionized gas? The Sun has magnetic field due to its ionized gas. Jupiter, Saturn, Uranus and Neptune might have high enough temperatures in their centra to have their gas inoized.
