How can a magnetic circuit with an airgap have a higher e.m.f in the secondary coil than the same circuit without the air gap?

I have a magnetic circuit with the same configuration as in the image, the primary coil has 203 turns and the secondary has 406 turns, how do I get a higher eletromotive force when there is an air gap across the magnetic circuit? If the reluctance is increased and the permeability is reduced shouldn't the emf also be less than without the air gap?
