Homework Help: Magnetic Flux

  1. Sep 4, 2010 #1
    1. The problem statement, all variables and given/known data

    A 3.0 magnetic field makes a 55deg angle with a square loop 25cm on a side

    2. Relevant equations

    MFlux = BACos(theta)

    3. The attempt at a solution


    Answer is to 2 sigfigs. This is a masteringphysics problem, and I'm wondering if I'm missing something here or if MP has the wrong answer stored.

    The relevant equation given by you is for a field making an angle θ with the vertical.

    In the problem the angle is with the plane of the coil. So

    MFlux = BAsinθ.
