Exploring the Power of Magnets

The video explores the fascinating world of magnets, starting with basic properties like attraction and repulsion. It demonstrates how magnetic fields can be visualized using iron filings. The discussion then shifts to Earth's magnetism, explaining the role of the inner and outer core in generating a magnetic field. Finally, it highlights how this magnetic field acts as a shield, protecting Earth from harmful solar radiation.
