A copper wire is 6.00 meter long and has a cross-sectional area of 1.00 x 10-4 m2. This wire forms a one turn loop in the shape of square and is then connected to a battery that applies a potential difference of 0.200 Volt. If the loop is located in a uniform magnetic field of magnitude 0.400 T, find the maximum torque that can act on it? The resistivity of copper is 1.7 x 10-8 Ω·m.
