Will the compass work on other planets and satellites in the solar system?

The compass is powered by magnetic poles. He seems to be “guided” by them. The compass will work on those planets that have these magnetic poles.

In the solar system, the planets with the most pronounced magnetic poles are Neptune, Jupiter and Earth.

Many factors affect whether a planet has a magnetic field. This includes factors such as the composition of the planet, core, lithosphere, and others. The state of aggregation of the planet and the chemical composition also matter.

There are planets with double magnetic poles (two south and two north).
