sähkömagnetismiin

Sähkömagnetismiin is the Finnish term for electromagnetism. It is a fundamental branch of physics that studies the electric and magnetic forces and their interactions. These forces are intimately related; a changing electric field can generate a magnetic field, and a changing magnetic field can induce an electric field. This interplay is described by Maxwell's equations, a set of four fundamental equations that unify electricity and magnetism.

Electromagnetism encompasses a wide range of phenomena. It explains the behavior of electric charges, the generation of electric currents, the properties of magnets, and the propagation of light, which is itself an electromagnetic wave. Applications of electromagnetism are ubiquitous in modern life, including electric motors, generators, radio communication, X-rays, and the very technology that allows us to display this text. Understanding sähkömagnetismiin is crucial for comprehending how much of the physical world operates.
