If it's mains operated probably not. Get a screwdriver, take it apart and find out. L

Call the local A&E, ask if anybody has been brought in slightly singed, with a screwdriver embedded in their forehead...

Indeed - ac motors tend to create their own magnetic field with an opposing coil.

As lemonie says ....often... you need to tell the ac coil where the magnets in a dc motor would be to be a magnet for the other coil to generate electricity. i.e. you need to excite that coil with some power, in order for the other coil to see a magnetic field and extract energy from the turbine. It's complicated - but really not impossible.
