In Fig. 30-42  a circular loop of wire 10 cm in diameter (seen edge-on) is placed with its normal  at an angle θ =30° with the direction of a uniform magnetic field  of magnitude 0.50 T. The loop is then rotated such that  rotates in a cone about the field direction at the rate 100 rev/min; angle θ remains unchanged during the process. What is the emf induced in the loop?
