a 200 loop square coil 0.8m to a side lies in the xy plane. The current in each loop of the coil is 8A clockwise. The coil is placed in a magnetic field B=2.0T x+4.0T y -0.5T z. Find..
a). magnetic moment (IA) of the coil.
b). the net force on the coil ( magnitude and direction).
c). the torque on the coil due to the magnetic field (magnitude and direction).
