Q2 (25P). An \( 3(\mathrm{~cm}) \times 4(\mathrm{~cm} \) ) rectangular conducting loop lies in the xy-plane. A direct current of 10 (A) flows in a clockwise direction viewing from the top. Find the magnitude of the magnetic flux density at the center of the loop [take \( \left.\mu_{0}=4 \pi \times 10^{-7}(\mathrm{H} / \mathrm{m})\right] \).
