Assignment:
A rectangular coil of wire, 22.0 cm by 35.0 cm and carrying a current 1.40 A, is oriented with the plane of its loop perpendicular to a uniform 1.50 T magnetic field as shown below.
a) Calculate the net force and torque which the magnetic field exerts on the coil.
b) The coil is rotated through a 30.0º angle about the axis shown, the left side coming out of the plane of the figure and the right side going into the plane. Calculate the net force and torque which the magnetic field exerts on the coil.
