The phenomenon of electromagnetic induction implies a production of induced

Electromagnetic induction is the process where a changing magnetic field induces an electromotive force (emf) or voltage in a conductor, which subsequently produces an induced current if the circuit is closed. According to Faraday's Law of Induction, the induced emf is directly proportional to the time rate of change of magnetic flux through the circuit. This phenomenon was famously demonstrated by Michael Faraday, who observed that while a steady magnetic field produces no effect, a current is induced in a coil whenever the magnetic field strength or flux changes, such as when a magnet is moved relative to the coil. Lenz's Law further specifies that the direction of this induced current is such that it creates a magnetic field opposing the original change in flux. Therefore, the phenomenon implies the production of current in a coil specifically when the magnetic field changes over time.
