Welcome to our demonstration of electromagnetic wave generation. Electromagnetic waves are created when electric charges undergo acceleration. When a charge oscillates back and forth, it creates changing electric and magnetic fields that propagate outward as electromagnetic waves. This is the fundamental principle behind all forms of electromagnetic radiation, from radio waves to light.
Now let's examine a simple antenna circuit that generates electromagnetic waves. The circuit consists of an AC voltage source connected to an antenna conductor and ground. When alternating current flows through the antenna, it creates oscillating electric and magnetic fields. The changing current direction produces expanding electromagnetic field patterns that propagate outward as radio waves.
