Magnetism and Navigation Concepts

Rajan shares his experience of a hiking trip with his dad and grandpa, where they navigated the forest using a magnet due to the lack of GPS. His grandpa demonstrated the directive property of magnets, which align in the north-south direction. When the magnet was cut, each piece became an independent magnet with its own poles. This experience taught Rajan the practical use of magnets for navigation, highlighting the importance of understanding magnetic properties.
