If a bar of copper is brought near a magnet, the copper bar will be repelled by the magnet (B). Copper itself is not magnetic, but it sets up electric currents when a magnet is brought close to a bar of copper. These electric eddy currents push the magnet away from the copper bar. Magnetism and electricity are related and the interaction between the copper and a magnet is used in power plants to generate the electricity that we use every day.
