It is proposed to use the Earth's magnetic field to turn a coil that is carrying an electric current. What is the maximum torque that can be produced in a rectangular coil of sides 4-m by 3-m, where the Earths magnetic field has a strength of 31 micro-tesla, and the current in the coil is 6 amperes. Write your answer in milli-Nm.
