Why do we need to have a soft iron core in transformer construction when the primary magnetic field is directly coupled with the secondary one?

Hi, In basic transformer theoretical explanations, there is a primary wound on one side of a soft iron core and secondary coil wound on other side of the core. The explanation will be like the...
