yes, but in simplistic terms nothing stops the ferrite rod to 
"concentrate" the magnetic field lines (from the surrounding air) inside 
the ferrite material, caused by the mu_r being much larger than the 
surrounding air. Regardless of the presence of the coil. Oh well if 
there's no coil there won't be a voltage being induced in the coil, it 
that's what the author wanted to say ?!
