A circular loop of wire can be used as a radio antenna. If an antenna with a diameter of 18.5cm is located a distance of 2.40km away from a from a source with a total power of 57.0kW at a frequency of 100MHz , what is the maximum emf induced in the loop? (Assume that the plane of the antenna loop is perpendicular to the direction of the radiation's magnetic field and that the source radiates uniformly in all directions.)
Use 3.00×10^8m/s for the speed of light in a vacuum and 1.26×10^-6N/A2 for the permeability of free space.
