Note that's the iron CORE, conveying the magnetic field, **NOT** the WINDINGS which are conveying the current!
And note, too, that modern, high-efficiency transformers use an alloy such as ferrite or mu-metal for their core. Those alloys' magnetic properties (high magnetic permeability) contain the magnetic field better, thus allowing less of it to expand into the region outside the transformer's secondary windings, allowing them to convert more of the energy transferred by the primary into the magnetic field back into electrical energy.
