This book describes how the phenomenon of magnetic attraction has been a topic of interest for more than a thousand years, and how our modern understanding of magnetism and its connection with electrical effects, has led to all sorts of applications. From the industrial revolution to the modern data age and medicine, magnetism has enabled all manner of technologies which have shaped our lives in uncountable ways. Moreover, the study of magnetism made a decisive contribution to advances in the understanding of the structure of matter in the first decades of the 20th century. Assuming no background in science, this book captures the magic of the magnet and explains how magnetism has had an inexorable influence on the course of humanity.
