What is Magnetism and Electromagnetism Overview about?
A magnet produces a magnetic field and can attract ferromagnetic materials like iron. It has two poles, north and south. Magnets attract materials like iron, cobalt, and nickel, and like poles repel while unlike poles attract. The magnetic field forms lines from the north to south pole. A plotting compass can be used to draw the magnetic field lines of a bar magnet on paper. Materials can become magnetized through induction when brought near a magnet.
