What Is The Function of A Core in A Transformer?

The main function of a core in a transformer is to provide a magnetic path linking the primary and secondary windings. Its high permeability allows changing magnetic flux to follow this path with relatively little magnetizing current. This supports effective magnetic coupling between the windings.
