Faraday's law of induction - Wikipedia
Faraday's law is a single equation describing two different phenomena: the motional emf generated by a magnetic force on a moving wire (see the Lorentz force), and the transformer emf generated by an electric force due to a changing magnetic field (described by the Maxwell–Faraday equation).

Calculate emf, current, and magnetic fields using Faraday’s Law. Faraday’s experiments showed that the emf induced by a change in magnetic flux depends on only a few factors. First, emf is directly proportional to the change in flux ΔΦ Δ Φ.
22.1: Magnetic Flux, Induction, and Faraday’s Law
2020年11月5日 · Faraday’s law of induction states that the EMF induced by a change in magnetic flux is EMF = − NΔΦ Δt, when flux changes by Δ in a time Δt. Faraday’s law of induction is a basic law of electromagnetism that predicts how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF).
Faraday's Law Of Induction: Definition, Formula & Examples
2020年12月28日 · Faraday's law of induction explains that a changing magnetic flux can induce a current in a loop of conducting material, and quantifies the induced EMF as equal to minus the rate of change of flux. In combination with Lenz's law, it can be used to describe the resulting current and its direction.
