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.

We do have to take them into account. Some iron takes on a magnetic field parallel to the earth’s fields when it is heated or struck percussively. This happens when it is built, so the direction it is facing when it is built will mess with the compass.

Some iron takes on these fields constantly

Ships are made of iron, so the ship’s compass has to adjust for this. There’s a lot of simple tech using magnets that do this in the Binnacle.

Here’s a video I recently watched about it:
