How science works 💡

I have been reading a book called “how science works” I have mainly been concentrating on electric and magnetism I have learnt that there are not just geographical poles but there are also some “magnetic” poles that exists on Earth check out this Wikipedia page about them.

https://en.wikipedia.org/wiki/Magnetic_pole

the poles change massively over the years there is a diagram in the book on the page of magnetism so that you can learn all about things to do with compasses!
