      So I was unaware that anything was happening to the earth’s magnetic field, so I googled it. and apparently, and I assume why you are asking this question, the earth’s poles are about to flip – but only soon in terms of geological time-scales, so actually it could happen in about 2000 years. which is interesting, but unlikely to effect my daily life so I’m not going to worry about it.

      As Vicky said that is a normal phenomenon that has happened many times in the past. If I remember correctly geologist could trace it through the geological eras by looking at magnetised deposits and seeing that every so often they flipped orientation.

      I wasn’t aware either, so I googled it like Vicky and found this interesting BBC article 🙂 http://www.bbc.com/earth/story/20141110-earths-magnetic-field-flips-more
