A circular coil of wire 8.20 cm in diameter has 15.0 turns and carries a current of 3.20 A. The coil is in a region where the magnetic field is 0.650 T .
Part A: What orientation of the coil gives the maximum torque on the coil ?
Part B: What is this maximum torque in part (A) ?
Part C: For what orientation of the coil is the magnitude of the torque 71.0 % of the maximum found in part (B)?
