4. Magnetic Torque:A loop with cross sectional area A = 1 cm2 is placed in a uniform magnetic flux density B¸ =1×10³ Wb/m²aligned with the z-axis.of 0 =-n|4 with the

x-axis, as shown.carrying 1 amp of current. The vertical axis of the loop is the torque acting on the loop if the face of the loop makes an angle is
