Effects of removing a soft iron core

An a.c. generator consists of a magnet rotating inside a cavity in a soft iron core. The output from the coil, wound on the iron core, is connected to an oscilloscope.
How would removing the soft iron core affect the output voltage shown on the oscilloscope screen?
Hmmm. I'm thinking that if the soft iron core was removed, it would be less easy for the magnet to magnetise and demagnetise. This means that energy will be wasted (as lost volts??), so the output voltage (e.m.f.) will decrease.
Is this correct?

In other words removing the core has the same effect as greatly reducing the number of turns in the coils or reducing the magnetising flux.
