EASY Multiple concept questions- How does a loop of wire in a generator produce AC

  1. May 27, 2008 #1
    1. The problem statement, all variables and given/known data

    How does a loop of wire in a generator produce alternating current?
    a.by creating current by rotating in an existing magnetic field?
    b.by creating a varying magnetic field with its rotational kinetic energy
    c.by rotating through areas of high and low electrical force



    An Electric Field produces a magnetic field even when there is no wire to conduct a current provided which of the following is also true?


    b.The electric field changes in time but at each instant is the same at every location.
    c.The electric field is changing as time passes.
    d.The electric field is different from place to place.



    2. Relevant equations



    3. The attempt at a solution

    for

    First question, I concluded it to be B.
    Second Question, From process of elimination, i said it was B also.
    Correct me if I am wrong :x
