What Has The Earth's Magnetic Field Ever Done For Us?

Have you ever wondered how your phone knows which way you’re facing, or what creates the northern lights? The answer lies in the Earth’s magnetic field – a vast, invisible shield generated deep within our planet and constantly shaped by solar activity.

This field not only guides navigation but protects life on Earth from harmful solar radiation. Yet it’s far from static: the magnetic poles drift, the field weakens and strengthens, and solar storms can disrupt satellites and power grids in an instant. In this talk, Gemma Richardson will explore how the Earth’s magnetic field works, how we measure and model it, and why space weather is becoming a critical challenge for our technology-driven world.
