Vaihtovirtakentälle
Vaihtovirtakentälle, often translated as alternating current field, refers to a time-varying magnetic field. Unlike a static magnetic field, a changing magnetic field is a fundamental concept in electromagnetism. This phenomenon is described by Faraday's law of induction, which states that a changing magnetic flux through a circuit induces an electromotive force (EMF), which in turn can drive an electric current.
The generation of a vaihtovirtakentälle typically involves the movement of electric charges or the fluctuation of
Applications of vaihtovirtakentälle are widespread. It is the operating principle behind many electrical devices, including transformers,
