Explain abot AC Generator very cleary that a 5th grade student should understand it

Hi,

A.C. generators or alternators (as they are usually called) operate on the same fundamental principles of  electromagnetic induction as D.C. generators.

    Alternating voltage may be generated by rotating a coil in the magnetic field or by rotating a magnetic field within a stationary coil. The value of the voltage generated depends on-

                     *  the number of turns in the coil.

                     *  strength of the field.

                     *  the speed at which the coil or magnetic field rotates.
