eletromagnéticos

Electromagnéticos refers to phenomena related to electromagnetism, the fundamental interaction that governs the behavior of electrically charged particles. It encompasses both electric and magnetic fields, which are intrinsically linked. Electric fields are generated by stationary electric charges, while magnetic fields are produced by moving charges (electric currents) and magnetic materials. A changing electric field can induce a magnetic field, and a changing magnetic field can induce an electric field, a principle famously described by Maxwell's equations.

This interaction is responsible for a vast array of phenomena in nature and technology. Light itself is a form of electromagnetic radiation, consisting of oscillating electric and magnetic fields propagating through space. Other forms of electromagnetic radiation include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays, differing in their wavelengths and frequencies.

Electromagnéticos are crucial for many everyday technologies. Electric motors and generators rely on the interplay between electric and magnetic fields. Radio communication, Wi-Fi, and mobile phone signals all utilize electromagnetic waves. Medical imaging techniques like MRI (Magnetic Resonance Imaging) also leverage electromagnetic principles. Understanding and harnessing electromagnéticos has been a cornerstone of scientific and technological advancement, shaping much of our modern world.
