3. A square loop of length 5.0 m on each side lying in the xy plane carries a current of 3.0 A in the clockwise direction as shown. It is in a uniform magnetic field given by \textbf{B} = 2.0\textbf{i} - 6.0\textbf{j} + 4.0\textbf{k} in Tesla. (a) Find the magnetic force exerted on each side of the loop. (Express each answer in terms of \textbf{i}, \textbf{j}, and \textbf{k}.) (b) What is the magnetic dipole moment? Again, express in terms of \textbf{i}, \textbf{j}, and \textbf{k}. (c) What is the potential energy of the loop in the field?
