electromagnético

Electromagnético refers to phenomena or devices related to electricity and magnetism. These two forces are intrinsically linked and can be generated by each other. An electric current produces a magnetic field, and a changing magnetic field can induce an electric current. This fundamental relationship is described by Maxwell's equations, which unify electricity and magnetism into a single framework.

Electromagnetic waves are a key manifestation of this connection. These waves consist of oscillating electric and magnetic fields that propagate through space at the speed of light. The electromagnetic spectrum encompasses a wide range of these waves, from radio waves and microwaves to visible light, ultraviolet radiation, X-rays, and gamma rays. Each type of wave differs in its wavelength and frequency, determining its properties and applications.

Electromagnetic devices are ubiquitous in modern technology. Examples include electric motors, which convert electrical energy into mechanical motion using magnetic fields, and generators, which do the opposite. Transformers utilize the principle of electromagnetic induction to change voltage levels in alternating current circuits. Radio transmitters and receivers rely on electromagnetic waves to communicate information wirelessly. Even everyday objects like magnets, compasses, and light bulbs are influenced by or are examples of electromagnetic principles. Understanding electromagnetism is crucial for many scientific and engineering disciplines, underpinning much of our technological infrastructure.
