An infinitely long straight wire is modified such that it includes a circular loop whose plane is perpendicular to the direction of the (otherwise long, straight) wire. The wire is insulated, and carries a current I, and the radius of the circular loop is R. Find the magnitude and direction of the magnetic field B at the center of the loop.
