Black Hole
May contain traces of nut
I just bought some neodymium magnets for a project - they arrived today and I've been fooling around with them. Out of a pocket full of change, I found some coins are attracted and others are not - do I have counterfeits???
I collected up all the coins I could find: out of 5x£1 (old), 3x50p, 7x20p, 1x10p, 2x5p, and 3x2p, one 10p one 5p and one 2p are magnetic.
