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.
