this is probably a pretty dumb question but i see the term polarity everywhere eg. "[FONT=&quot]as the induced emf changes polarity with every half turn of the coil" with ac generators. a friend asked me this and i had no idea...what does polarity actually mean?? thanks.[/FONT]

Polarity, in this sense, is simply the direction in which the electrons are flowing, i.e. which end of the coil we call positive and which we call negative
