Electromagnetic technology refers to the use of electromagnetic fields and waves to transmit and manipulate energy and information. This technology is foundational in various applications, including radio communication, television broadcasting, and wireless internet. It relies on the principles of electromagnetism, which describe how electric charges create magnetic fields and vice versa. Devices such as radios, microwaves, and MRI machines utilize electromagnetic technology to function effectively. These devices convert electrical energy into electromagnetic waves, allowing for the transmission of signals or the generation of images. Overall, electromagnetic technology plays a crucial role in modern communication and medical imaging.
