the strongest magnet in the world boasts 900 times the earths magnetism, so why wouldn’t a compass point towards those superior magnets?

Question

Also does anyone know how those ultra strong magnets are affecting our planet if at all?

Edit: sorry the [link](https://imamagnets.com/en/blog/what-is-most-powerful-magnet/#:~:text=The%20world’s%20most%20powerful%20magnet%20is%2044.14%20Teslas.&text=This%20super%20magnet%20has%20a,we%20find%20in%20a%20hospital) says 900,000 times the earths magnetism

Edit 2: Thank you wonderful people for clearing that up. Your minor support did more for my mental health than you realize not just for the knowledge but also the general support from the community. Y’all are amazing.

Answer 1

It doesn’t have 900 times more magnetism, it’s magnetic field strength at the surface of the magnet is 900 times stronger than that of the earth at the same point.

Field strength drops as the inverse cube of the distance. So the earth’s magnetic field is stronger once you get more than 10m away from the magnet.

And as for the effect on the earth – zero. The planet is really, really big, and ten metres is really no distance at all in comparison.
