The earth's magnetic field
WebSep 4, 2024 · Saturn's magnetic field has north and south poles, like those on a bar magnet, and the field rotates with the planet. On Jupiter and Earth, the magnetic fields are slightly tilted with respect to the from the planets' rotation axes – this tilt is the reason we say compass needles point to "magnetic north" rather than true north. WebA magnetic field is a picture that we use as a tool to describe how the magnetic force is distributed in the space around and within something magnetic. [Explain] Most of us have …
