Do not dynamos, alternators and transformers rely on currents induced
into *conductors* by changing magnetic fields? Please see 'Faraday's
Law of Induction' regarding the current induced into a conductor.

Actually it is explained in the opening remarks of that article where it
says that an EMF is produced.
