Using new MagSafe Charger on a metal surface.
Hi. So I've just got my new MagSafe Charger which I intent to have on my bedside table which is made of metal - the charger sticks to the metal like a magnet - this is actually really good as it will stay in place and I can just grab my new phone off it but I just wanted to check it's safe and okay to use it on a metal surface - sorry if it sounds like a silly question.
