In Fig. 30-56, a circular loop of wire 10 cm in diameter (seen edge-on) is placed with its normal `vecN` at an angle `theta` = 20° with the direction of a uniform magnetic field `vecB` of magnitude 1.5 T. The loop is then rotated such that `vecN` rotates in a cone about the field direction at the rate 100 rev/min, angle `theta` remains unchanged during the process. What is the emf induced in the loop?

Explanation

Zero
