In this quick revision of Class 6 Science, Chapter 4: Exploring Magnets, we dive into the mysterious world of magnetism through the story of Reshma, a young writer trying to save her fictional sailors lost in a storm. In her search for a solution, she discovers the magnetic compass—an invention that changed history.

Join us as we explore the fundamental rules of magnetism: how magnets only attract certain materials like iron and nickel, the power of magnetic poles (North and South), and the crucial law that "opposites attract, and likes repel." We also uncover how the Earth itself acts as a giant magnet, guiding compasses everywhere, and share a fun DIY experiment to build your own compass at home!
