What is the working principle of an Alternator ?

According to Faraday’s Right Hand Law of Electromagnetic Induction, clockwise current is induced in the conductor of a magnetic field as a result of relative motion between such conductor of magnetic field. Similar to the basic principle of DC Generators, the working principle of an alternator is also based on Fleming’s Right Hand Law of Electromagnetic Induction.
An alternator is a type of electrical generator which turns mechanical energy into electrical energy in the form of an alternating current (which could be a rotating alternating current too). An electric current is generated and born to the DC via a rectifier when this AC (Alternating Current) passes through a magnetic field. At this point, a voltage regulator stabilizes the voltage at the correct level to avoid any adverse effects of a heavy electrical load.
Parts World USA has a wide range of alternators to offer, which replace NAB300 and LRA109.
