Q- 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 in to the plane of the coil.
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 passing through center and parallel to smaller sides. Calculate the net force and torque which the magnetic field exerts on the coil.
