I have been thinking about Earth’s magnetic field and magnets in general. I read a lot about both. It came down to the fact that I don’t understand any of it. I don’t know why anything is magnetic. I don’t know why the planets have magnetic fields and I don’t know where magnetism comes from.
I do know that I found pretty pictures and I drew a couple of pictures for you.
Magnets have two poles. A north pole and a south pole. These poles are also callled + and -. Poles that are the same push each magnet away from the other one. Poles that are opposite, bring the magnets together.
Just to add to the confusion, this is a NASA picture of the Earth’s magnetic field between what is called reversals. There is evidence that the magnetic field has changed over a long period of time. North became south and south became north. Then it changed back. It must have been hard to give directions when this happened.
That’s it for today’s confusing facts.
