    In Jupiter: The magnetic field and magnetosphere

    The axis of the magnetic dipole is offset by a tenth of Jupiter’s equatorial radius of 71,500 km (44,400 miles) from the planet’s rotational axis, to which it is indeed inclined by 10°. The orientation of the Jovian magnetic field is opposite to the present orientation of Earth’s field,…

    In geomagnetic field: Dipolar field

    The magnetic field lines shown in the bar-magnet figure are not real entities, although they are frequently treated as such. A magnetic field is a continuous function that exists at every point in space. A field line is simply a means for visualizing…

    In Saturn: The magnetic field and magnetosphere

    … resembles that of a simple dipole, or bar magnet, its north-south axis aligned to within 1° of Saturn’s rotation axis with the centre of the magnetic dipole at the centre of the planet. The polarity of the field, like Jupiter’s, is opposite that of Earth’s present field—i.e., the field lines…
