Hugo, a great question. I think the world is magnetic but I am not sure how we can find out if it is. Let me ask my friends. They should be able to give me an answer in a few hours time. I think it is something to do with compasses.
Hugo, I think you will need some equipment ……. a small bar magnet and a square of polystyrene or woo. This will mean that you can float the magnet on some water.
