In the book “CHARGE: Why Does Gravity Rule?” by theoretical physicist Frank Close, he delves into the fundamental forces that shape our world, exploring the relationship between positive and negative charges and the impact on gravity. Magnetism, a tangible force, is a manifestation of electricity and plays a crucial role in our world. From the Earth’s liquid core generating a magnetic field to the magnetic properties of rocks containing iron, magnetism is ever-present. The interaction between a bar magnet and iron filings demonstrates the magnetic force’s behavior, showcasing its influence on Earth’s magnetic poles. Legends of ancient Greece and discoveries in the Iron Age highlight humanity’s long-standing knowledge of magnetism. Overall, magnetism has been essential for centuries, influencing our understanding of the world. This excerpt is from Close’s book, “CHARGE: Why Does Gravity Rule?” published by Oxford University Press.
