Final answer:
Hans Orsted was the first scientist to describe electromagnetic induction, discovering that an electric current can be produced by a moving magnet. His work was built upon by other scientists.
Step-by-step explanation:
Hans Orsted was the first scientist to describe electromagnetic induction. He conducted experiments and discovered that an electric current can be produced by a moving magnet. This discovery laid the foundation for understanding the relationship between electricity and magnetism. Orsted's work was later built upon by other scientists, including Faraday, who developed a mathematical theory to explain electromagnetic induction.
