Electrical energy is particularly useful for the reason that it can be distributed and converted to other desired forms of energy due to its inherent versatility. At present, the main source of electrical energy is the mechanical form, either direct (as in hydraulic turbine) or from heat (as in steam turbine) or from chemical energy (as in batteries). A convenient direct method of converting mechanical to electrical energy is through the use of mechanical force when a current -carrying conductor is situated in a magnetic field. The movement of the conductor through a polar magnetic field having consecutive reversals of polarity results in the production of an emf which changes sign in ...
