The discovery of magnetism
The human fascination and understanding of magnetism began thousands of years ago. From the mysterious properties of lodestone used in compasses to the discovery of magnetic fields that guide birds and other animals in their migrations, the roots of magnetism are deep and complex. By the timched ane we reacient Greece, philosophers like Plato and Aristotle had cataloged the mystique surrounding magnets, predicting it came from an invisible "magnetic fluid" powering their captivating properties.
During the medieval period, mariners adopted magnetic compasses for navigation, while ancient Chinese and Greeks rudimentary used magnetized iron rods as early forms of magnets. It wasn’t until the 18th century that a Frenchman, named Constant Geyl, named the new use of the word "magnetism" for the invisible, combined magnetic force.
