  • Page 5: Generator Fundamentals

    Section 1 GENERATOR FUNDAMENTALS MAGNETISM NOTE: The "right hand rule" is based on the "cur- rent flow" theory which assumes that current flows from positive to negative. This is opposite Magnetism can be used to produce electricity and the "electron" theory, which states that current electricity can be used to produce magnetism.

  • Page 6: A Simple Ac Generator

    Section 1 GENERATOR FUNDAMENTALS A SIMPLE AC GENERATOR Figure 1-4 shows a very simple AC Generator. The CURRENT VOLTAGE generator consists of a rotating magnetic field called a ROTOR and a stationary coil of wire called a STA- TOR. The ROTOR is a permanent magnet which con- sists of a SOUTH magnetic pole and a NORTH mag- netic pole.
