Magnetic flux and Faraday's law (article) | Khan Academy
An induced emf causes electric current to flow through the loop. Faraday's law connects the emf ( E) induced in a loop to the rate of change of magnetic flux through the loop: | E | = | Δ Φ Δ t |. If the magnetic flux isn't changing, then Δ Φ Δ t = 0 and no emf is induced. The flux must be changing to produce an emf.
