Remove the magnet, and the paperclip stops acting so magnet-like. Do magnets deplete over time? Demagnetisation is a slow process but magnets can lose their strength over time. This generally happens in two ways. So-called permanent magnets are constructed from materials made up of magnetic domains, in which atoms...
