The magnetosphere is embedded within the plasma of the solar wind, which carries the interplanetary magnetic field.

Among other accomplishments, the probe confirmed the existence of interplanetary magnetic fields.

But it is known that during spring and autumn, the interplanetary magnetic field and that of Earth link up.

However, according to spacecraft observations the interplanetary field at the Earth's location is around 5 nT, about a hundred times greater.

Finally, a polar-ring current has been derived from the observations which depends on the polarity of the interplanetary magnetic field.

Thus, it effectively measured only the changes in the interplanetary field.

In fact, it throws the interplanetary magnetic fields way out of kilter.

The polar cap ionosphere is directly linked to the interplanetary magnetic field carried by the solar wind.

The interplanetary magnetic field, embedded in the solar wind, also deflects cosmic rays.

They probably represent self-contained structures that have detached from the interplanetary magnetic field.
