Ferrous content is only meeded to induce a magnetic field in the material.

It's not a case of the air becoming magnetic. It's that magnetic fields affect 
molecular behaviour...

Check up on Plasma bottles...

> Electricity does move air, so why not magnets??

'cause the air does not (hopefully) contain iron, the key ingredient to 
magnetism. The sound is likely the magnets resonating, or more simply the coils 
vibrating as they are pulsed.
