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.

The field size of earths magnetic field is very large, those super magnets that are difficult to pull apart however are much smaller. Scale such an object up to a planetary size and a compass would in fact react to such a large field.
So in this case size matters more than strength, as a magnet that is able to create a magnetic field on a planetary scale is going to allow compass needles to detect the field where a small magnet that isn’t the size of a planet requires the compass to be within the field, which if you hold the compass close enough that will occur. Basically imagine the magnet is the entire planet and the compass is close enough to the very big magnet that this is why it works in such a manner.
