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 magnet in the link looks like it’s about 1 meter tall. For the sake of simplicity let’s assume it is a 2 meter diameter sphere.
Magnetism changes with the cube of distance. So measuring 1 meter away from the center is 1000x less powerful than 100 cm from the center.
The earth’s radius is ~6,300,000 meters (6,300 km). This is 6 orders of magnitude to 1 meter. If you check the above line that means at 1 meter we would just divide the field strength by a number with **eighteen** zeros. OP’s edited number has 5 zeros.
Thus, using orders of magnitude we can quickly determine the Earth’s magnetic field is about *10,000,000,000,000x* stronger than this magnet at about 1 meter if it were replaced with a single point.
