2) A conductor consists of a circular loop of radius $R=15\mathrm{cm}$ and two long, straight sections as shown in Figure. The wire lies in the plane of the paper and carries a current $I=1A$. Find the direction and magnitude of the magnetic field at the center of the loop. (HINT: One is an infinitely long wire and use the equation to calculate its magnetic field at a distance of R. For the circular loop, use the answer of the previous question. Check their direction to find the total magnetic field)
