Magnetism and Its Wonders

The video explores the fascinating world of magnets, starting with their basic properties and how they can attract or repel objects. It delves into the concept of magnetic fields and demonstrates experiments to show how magnets interact with different materials. The video also highlights the use of magnets in tricks, such as making them float, and explains how animals like turtles use Earth's magnetic field for navigation. Finally, it provides a step-by-step guide to building a simple compass using a magnet.
