A radiowave has a maximum magnetic field induction of $10^{-4} T$ on arrival at a receiving antenna. The maximum electric field intensity of such a wave is |
zero $3 × 10^4 V/m$ $5.8 × 10^{-9} V/m$ $3.3 × 10^{-13} V/m$ |
$3 × 10^4 V/m$ |
$E_{max} = c B_{max} = 3\times 10^8 \times 10^{-4} = 3\times 10^4 V/m$ |
