Magnets do not have a physical line that divides them into north and south poles; instead, the magnetic field is continuous. This division is conceptual, as the poles are not equal in strength or size. The field lines extend from the north pole to the south pole, creating a magnetic field that interacts with other magnetic fields. For a deeper understanding of magnetism and how magnets react to each other, several educational websites and resources are recommended. Exploring these resources can provide clearer insights into magnetic interactions and field dynamics.
