Introduction to Bar Magnets
Bar magnets are one of the most common types of magnets. They are rectangular in shape with two distinct poles – a north pole and a south pole. The magnetic field lines of a bar magnet emerge from the north pole and enter the south pole, creating a magnetic field around the magnet. Bar magnets are used in a wide range of applications, including electric motors, generators, magnetic separators, speakers, and educational purposes. Their simple yet effective design makes them a fundamental component in many industries. Bar Magnets
