James Clerk Maxwell presents electromagnetic field theory

In 1865, James Clerk Maxwell presented his groundbreaking electromagnetic field theory, fundamentally transforming the understanding of electromagnetism. Maxwell’s equations, a set of four partial differential equations, described how electric and magnetic fields interact and propagate as electromagnetic waves. This theoretical framework laid the foundation for modern physics and electrical engineering. For amateur radio operators, Maxwell’s work is seminal, as it elucidates the principles underlying radio wave propagation, antenna design, and signal transmission. Maxwell’s contributions enabled the development of wireless communication technologies, influencing pioneers like Hertz and Marconi, and continue to be essential in advancing the capabilities and understanding of amateur radio today.
