PRESENTATION: A simple pendulum is constructed with a powerful magnet placed close to an iron wire. The initial setting keeps the magnet in equilibrium in a position of maximum amplitude close to the wire. If the wire is heated with a candle, or, alternatively, an electric current is made to pass through it, it behaves as a paramagnetic material and ceases to be attracted by the magnet.
