Magnetic flux
Videos
In physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface. It is usually denoted Φ or ΦB.

Faraday's law of induction

In electromagnetism, Faraday's law of induction describes how a changing magnetic field can induce an electric current in a circuit. This phenomenon, known as electromagnetic induction, is the fundame

…through a loop of conductive wire will cause an electromotive force (emf), and therefore an electric current, in the loop. The relationship is given by Faraday's law: E = ∮ ∂ Σ ( E + v × B ) ⋅ d ℓ = − d Φ B d t , where: E is the electromotive force (emf…
