Homework Help: Electric Flux

  1. Mar 18, 2007 #1
    1. The problem statement, all variables and given/known data
    A square loop with resistance 15 ohms is placed perpendicular to a time varying magnetic field; the loop is 8.2 cm. The magnetic field is changing with a rate of 3.4 x 10^-7 T/s.
    -Draw the loop, magnetic field, and current in the diagram
    -calculate the rate at which the magnetic flux threading the loop changes.
    -calculate the current circulating the loop.


    2. Relevant equations

    I=Bvl/R

    3. The attempt at a solution

    Are you working from a book? You need the equation for flux (hint: it's related to magnetic field and enclosed area), and Faraday's Law.
