This program looks at physics principles behind AC and DC generators. The relationship between a changing magnetic field and induction of electric current is examined, with a hand rule introduced to predict the generator effect in a linear length of conductor. The behavior of a rotating coil in a magnetic field leads to construction of an AC motor. Alternators and split-ring commutator generators are introduced. 20 minutes.
