Earth's Magnetic Field

The video explains magnetism as an invisible force caused by electron motion, creating magnetic fields. Earth's magnetic field, due to its iron and nickel core, acts like a giant magnet with north and south poles. A compass aligns with this field, aiding navigation. Importantly, Earth's magnetic field shields the planet from harmful solar wind and radiation, protecting life and technology.

Explain the significance of the north and south poles of Earth.
