Question: A small coil has a cross section of 5.0 cm2 and consists of 8 turns of wire.
Part A: If the loop carries a current of 80 mA, what is the torque required to hold the loop at right angles to a field of B = 0.010 T?

Any help I can get on this question is greatly appreciated! I'm not too familiar with this question.
