How a transformer works

A labelled transformer schematic showing a primary coil connected to an AC supply, a secondary coil connected to a load, a soft iron core, and changing magnetic flux through the core A transformer changes the amplitude of an alternating voltage using electromagnetic induction. It has a primary coil, a secondary coil, and a soft iron core that guides magnetic flux between them.
