An extremely long straight wire carries a current of 15A, and there is a circular loop of radius 3cm along the wire as shown below. Approximating the wire as infintely long, determine the magnitude and direction of the magnetic field at the center of the loop generated by the current. Assume the magnetic field is coming out of the page from the center of the circle.
