    What is the magnitude of the magnetic field at the center of the arc?

    I guess I thought that this equation was for semi-finite straight wires as well...I don't know what the equation for it is if it is not this...

    What is the magnitude of the magnetic field at the center of the arc?

    A current I = 3 A flows through a wire perpendicular to the paper and towards the reader at A and back in the opposite direction at C. Consider the wires below the plane at A and C to be semi-infinite. In the figure, L1 = 3 m, R = 6 m, and L2 = 6 m and there is a B = 2.37 T magnetic field into...
