The wave from a radio station transmitting at 820 kHz (this is in the AMband) falls on a loop antenna made of 20 coils of wire of radius 10cm. Assumethat the magnetic field is perpendicular to the plane of the coils (see the figurebelow) and, at the coils, takes the form B = (1.0 x 10-6T) sin [(27f)t] ĵ. Find theEMF induced in the loop. Include the direction of the EMF, specified asclockwise or counterclockwise as viewed from the right looking left at the loop.Hint: d(sin at)/dt = a cos(at)0B
