For one of his tricks, he placed a suitcase on the stage and asked the biggest, strongest man in the audience to try to lift it up. As the man approached the stage, the magician waved his arms and proclaimed that he had taken away all of the man s strength. The strong man tried, but he couldn t budge the suitcase. Then the magician asked a small child to lift the suitcase. The child easily picked up the suitcase and carried it off the stage. Robert-Houdin was experimenting with a new technology at the time: an electromagnet. Explain how you think Robert-Houdin used an electromagnet to make this trick work.
