2. William Gilbert’s “De Magnete”: Coining the Term “Electric”
English physician and natural philosopher William Gilbert made major contributions to the study of electricity and magnetism in the late 16th century. Published in 1600, his foundational work “De Magnete,” signalled a change in scientific knowledge of these phenomena. Gilbert’s most famous contribution was the name “electric” to characterise the attraction-exhibiting quality of some materials following rubbing. Derived from the Greek word “elektron,” “amber,” this vocabulary offered a consistent approach for analysing and debating these enigmatic powers. Gilbert produced work well beyond simple nomenclature. He methodically recorded the electrical characteristics of many materials by running extensive experiments with them. His experiments showed that friction may “electrocite many drugs, not only amber.” This realisation broadened the field of electrical research and disproved the conventional wisdom that said the amber effect was special or mystical. Gilbert also made the essential difference between magnetic and electric attractions, which had sometimes been confused by past researchers. He demonstrated that although magnetic effects confined to a few materials, such as lodestone, electrical effects may be generated in a great variety of compounds. This distinction was a major step towards comprehending the basic character of these forces. Gilbert’s rigorous approach to testing and his focus on empirical data establish a new benchmark for electrical field scientific investigation. His contributions prepared the path for the electrical revolution that would develop in the next centuries, therefore enabling other scientists to expand upon them. Beyond its immediate topic, “De Magnete” had an impact on the scientific method and promoted a more methodically approach to the study of natural events.
