Homework Help: Biot Savart Law question

  1. Mar 6, 2016 #1
    1. The problem statement, all variables and given/known data

    A rectangular loop with dimensions 4.20 cm by 9.50 cm carries current I. The current in the loop produces a magnetic field at the center of the loop that has magnitude 3.60×10−5T and direction away from you as you view the plane of the loop.
    2. Relevant equations
    b = mu_0 I L/ 4pi*r ,where l is (a/bsqrt(a^2+b^2)) and
    (b/asqrt(a^2+b^2));
    a = .042m
    b = .095m
    3. The attempt at a solution
    i think i just put the given values into the equation, then solve for I, but i'm not sure if i'm setting it up right

    First write out the general formula for a magnetic field due to a finite wire with current. The formula you write there is not correct.
