A copper wire is 8.00 m long, and has a cross-sectional area of 1.00 × 10–4 m2. This wire forms a 1turn loop in the shape of a square and is then connected to a battery that applies a potential difference of 0.100 V. If the loop is placed in a uniform magnetic field of magnitude 0.400 T, what is the maximum torque that can act on it? The resistivity of copper is 1.70 × 10–8 Ω · m. Define Resistivity
