The topic of magnetism came up in our class, and in this lecture, my teacher said that the north geographic pole in our compass (or magnets in general) points towards the south magnetic pole of Earth. Adding the fact that our magnetic field flips every hundred thousands of years, how will it affect us and our daily living? The most I can think of is that our current compasses will become obsolete. What are your thoughts?
Thank you for answering!!

The time when it happens will be nasty, because for a few 100 years the magnetic field of earth will be very weak during the switching event.
In that time radiation from the sun would disturb all electronics on earth, so we’d need to manually shield every single device.
But once it’s finished there wouldn’t be a really big difference to before except that we’d have to relabel old compasses
