Oersteds Experiment Mugs

Description: A detailed scientific illustration of a wire carrying a current over a compass whose needle swings away from north, the experiment that linked electricity and magnetism, set against a deep dark background. In 1820 the Danish physicist Hans Christian Ørsted noticed that an electric current deflects a nearby compass needle. This discovery revealed the link between electricity and magnetism and launched electromagnetism. A gift idea for physicists, engineers and physics students, and a striking addition to a study, lab or office wall.
