    Magnetic Field of rectangular current loop

    It's third year...E&M 2..any help? I do know there is symmetry of the horizontal and vertical components, and they all add up to give the total magnetic field

    Magnetic Field of rectangular current loop

    Well I know how to solve it for a square loop theta 1 =-theta2=45 degrees = sqrt2*Mu*I/Pi*R Now for a rectangle I think that theta1=-theta2 (for sides B1=B3) = -b/(sqrt(a^2+z^2) and theta1=theta2 (for sides B2=B4) = a/(sqrt(b^2+z^2) and than I add them together but I'm not sure
