I Review I Constants
A circular loop of wire can be used as a radio antenna. If
an 21.6-cm-diameter antenna is located 2.00 km from a
88.9 MHz source with a total power of 65.2 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.
