A magnet is an object or material that produces a magnetic field. This field attracts or repels other magnetic materials like iron, nickel, and cobalt. Magnets have two poles, a north pole and a south pole, and opposite poles attract, while like poles repel. Think of it like having two ends, one that pulls and one that pushes. They are used in countless applications, from holding notes on your fridge to powering electric motors. It's all about attraction and repulsion.
