Who proposed the Theory of Electromagnetism?

The Theory of Electromagnetism was primarily formulated by James Clerk Maxwell in the mid-19th century. Maxwell's work unified electricity and magnetism into a single theoretical framework through a set of equations known as Maxwell's equations. These equations describe how electric and magnetic fields are generated and altered by each other and by charges and currents. This revolutionary approach not only provided a deeper understanding of electromagnetic phenomena but also laid the groundwork for many modern technologies, including radio, television, and electrical engineering.

The contributions of scientists like Hubble, Kepler, and Galileo are significant in their own rights, but they focus on different areas of science. Hubble is renowned for his work in astronomy, particularly for concepts related to the expansion of the universe. Kepler is famous for his laws of planetary motion, which describe the orbits of planets. Galileo is known for his contributions to observational astronomy and kinematics but did not work directly on electromagnetism. Thus, while these scientists made lasting impacts on their respective fields, it was Maxwell whose insights specifically advanced the understanding of electromagnetic phenomena.
