A circular loop of wire can be used as a radio antenna. If an 19.8-cm-diameter antenna is located 3.00 km from a 88.9 MHz source with a total power of 60.1 kW, what is the maximum emf induced in the loop? The orientation of the antenna loop and the polarization of the wave are as shown in (Figure 1). Assume that the source radiates uniformly in all directions. Figure In vicinity of loop, wave propagates in +x-direction. In vicinity of loop. E has only a y-component and B has only a 2-component.

Current Attempt in Progress The power radiated by the sun is 3.9 × 10²6 W. The earth orbits the sun in a nearly circular orbit of radius 1.5 × 10¹¹ m. The earth's axis of rotation is tilted by 23.4° relative to the plane of the orbit (see the drawing), so sunlight does not strike the equator perpendicularly.
