Did you know that magnets are used in computer data storage, compasses, doorbells and alarm systems, microphones and speakers, motors, electrical generators and electrical transformers? They are also used to levitate objects, including trains that operate via magnetic propulsion. Each magnet has a North pole and a South pole. When you put North by North or South by South, it repels. If you put North by South, it attracts.
