because a reed switch is like an electromagnet so the purpose of it is that it will spring open when you remove the magnet. Iron is better because it looses it's magnetism quicker, whereas steel strips don't loose their magnetism as quickly so when you do remove the magnet, a steel strip would stay closed for a while longer rather than open straight away :D
