1. The problem statement, all variables and given/known data In the figure below, a circular loop of wire 12 cm in diameter (seen edge on) is placed with its normal at an angle θ = 30° with the direction of a uniform magnetic field B of magnitude 0.60 T. The loop is then rotated so that N rotates in a cone about the field direction at the rate 160 rev/min; angle θ remains unchanged during the process. What is the emf induced in the loop? Figure: http://imageshack.us/photo/my-images/854/webassign.jpg/ 2. Relevant equations EMF = BAcos(theta) or EMF = d(BAcos(theta))/dt 3. The attempt at a solution I converted 160 rev/min to rev/sec and then to rad/sec, getting 16.755 rad/sec. I then plugged the given data into the 2nd equation above (trying both positive and negative signs) and it's still incorrect. Any help would be appreciated.
