You are given a VHF television antenna (the antenna type is a magnetic loop antenna) and asked to determine the signal strength going into the reciver from the antenna. The antenna is a circular 1-turn loop of diameter 12.9 cm. The magnetic field of the TV signal is perpendicular to the plane of the loop, and is essentially uniform over the area of the loop at any given instant. If the magnetic field is given by B = Bo sin (21 ft) where Bo = 6.9 nT and f = 258.8 MHz (megacycles/sec), the maximum value of the emf induced in the loop, E, is the strength of the signal going into the reciver in mv. What is this signal strength E? mV
