Homework Help: Emf in a rectangular loop

  1. Apr 10, 2008 #1
    [SOLVED] Emf in a rectangular loop

    1. The problem statement, all variables and given/known data
    A rectangular loop (area = 0.15 m^2) turns in a uniform magnetic field, B = 0.16 T. When the angle between the field and the normal to the plane of the loop is pi/2 rad and increasing at 0.70 rad/s, what emf is induced in the loop?

    2. Relevant equations

    EMF=-N (delta flux/delta time)

    3. The attempt at a solution

    Flux= 0.16T * 0.15 m^2 = 0.024

    Not sure what to do for the EMF.
    Divided pi/2 radians by 0.70 rad/s to find time of 2.24 seconds. Then divided the flux by the time so... 0.024/2.24=0.011V

    Thanks in advance for your help!

    Actually, I was making a silly mistake...answer was off by one decimal place because I misread the area to be 0.015 m^2. Pretty simple problem lol
