Definition of «electromagnetic»

The term "electromagnetic" refers to something that is related to or caused by electromagnetism. Electromagnetism is a fundamental force in nature which involves the interaction between electricity and magnetism, resulting from the movement of charged particles such as electrons. When an electric current flows through a wire, it generates a magnetic field around the wire. Conversely, when a magnetic field changes near a conductor, it can induce an electrical current within that conductor.

Electromagnetic phenomena include things like electricity, magnetism, light and radio waves. The word "electromagnetic" is often used to describe devices or technologies that use these principles such as generators, motors, transformers, wireless communication systems, etc. In summary, the term electromagnetic refers to anything related to the interaction between electricity and magnetism, which are fundamental forces of nature.

Usage examples

  1. Electromagnetic waves, such as radio waves, microwaves, and X-rays, are used in various communication and imaging technologies.
  2. Electromagnetic radiation plays a crucial role in wireless communication, allowing us to send and receive information through devices like smartphones and satellites.
  3. Magnetic resonance imaging (MRI) utilizes powerful electromagnetic fields to generate detailed images of the internal structures of the human body.
  4. Electromagnetic induction is the principle behind the functioning of electrical transformers, which are used to step up or step down voltage levels in power distribution systems.
  5. Electromagnetic interference (EMI) can disrupt electronic devices and cause signal distortion. Shielding techniques are employed to prevent or minimize such interference.
  6. Electromagnetic spectrum refers to the entire range of electromagnetic waves, from radio waves with long wavelengths to gamma rays with extremely short wavelengths.
  7. Electromagnetic brakes use magnetic fields generated by electromagnets to control the braking force in vehicles, industrial machinery, or elevators.
  8. Electromagnetic fields produced by electric power lines are subject to scrutiny due to potential health hazards, although scientific consensus regarding associated risks remains controversial.
  9. Electromagnetic propulsion is a technology that uses electromagnetic forces to propel or levitate vehicles, such as Maglev trains or experimental spacecraft.
  10. Electromagnetic theory, formulated by James Clerk Maxwell in the 19th century, established the fundamental understanding of the relationships between electric and magnetic fields.
