## Homework Statement

An AM Radio station broadcasts isotropically(equally in all directions) with an average power of 4.00kW. A dipole receiving antenna 65.0cm long is at a location 4.00 mi from the transmitter. Compute the amplitude of the emf that is induced by this signal between the ends of the receiving antenna.

## Homework Equations

[tex]P[/tex][tex]_{avg}[/tex]=S[tex]_{}avg[/tex]A

E[tex]_{max}[/tex]=[tex]\sqrt{\mu_{\circ}[/tex]cP[tex]_{avg}[/tex]/2[tex]\pi[/tex]r^2}

B[tex]_{max}[/tex]=[tex]\frac{E_{max}}{C}[/tex]

## The Attempt at a Solution

Used the avg power to find the E[tex]_{max}[/tex] to be .0058V/M. tHen used this to find the B[tex]_{max}[/tex] to be 1.9305*10^-11T. I am not sure how to calculate the emf from this.
