The wave from a radio station transmitting at 820 kHz (this is in the AM band) falls on a loop antenna made of 20 coils of wire of radius 10cm. Assume that the magnetic field is perpendicular to the plane of the coils (see the figure below) and, at the coils, takes the form Ả = (1.0 x 106 T) sin [(2ïf)t] ĵ. Find the EMF induced in the loop. Include the direction of the EMF, specified as clockwise or counterclockwise as viewed from the right looking left at the loop. Hint: d(sin at)/dt = a cos(at) o B
