I know I probably didn’t phrase this correctly, but my English grammar is limited in this sort of stuff . I hope someone understands what I’m trying to say hah

Imagine a planet like the Earth. If it had a magnetic field 3d all around, it would protect agains solar radiation all the time all around. If it had 2d it would protect just one slice of tje surfere while the other is bombarded with cancer Rays.
Now. Look at the acutal Earth planet we live on. What kind of magnetic anti cancer solar Ray protection do we have? All around baby, so we must infer that Earths magnetic field (and fields in general) be the all-around and ‘3d’.
Unfortunalty we have a hard time to easely experiment on it at home. Yoy know the experiment whare yoy place a bar magnet under a piece of paper and then drizzle small Iron filings over it to show the magnetic lines? Thats a 2d slice of the magnetic field lines that goes all around. You can clean it up, turn the bar magnet and repeat, now yoy have a visual for these other 2d slice of the bar magnets magnetic field… continue to do this with in all of the 3d space around the magnet and not just the now 2 slices if the field, and you can see the 3d field all around the bar magnet.
