What is primary induction?

Primary induction refers to the initial phase in the process of electrical generation, particularly in electrical machines like generators and Transformers, where an alternating current (AC) is induced in the primary winding. This induction occurs due to the changing magnetic field created by the current flowing through the primary coil, which then produces a magnetic flux that induces an electromotive force (EMF) in the secondary winding. The principle is based on Faraday's law of electromagnetic induction, which states that a change in magnetic flux can generate an electric current.
