A point source of electromagnetic radiation has an average power output of \( 800 \mathrm{~W} \). The maximum value of electric field at a distance \( 3.5 \mathrm{~m} \) from the source will be \( 62.6 \mathrm{~V} / \mathrm{m} \), the maximum value of magnetic field will be
(a) \( 2.09 \times 10^{-5} \mathrm{~T} \)
(b) \( 2.09 \times 10^{-6} \mathrm{~T} \)
(c) \( 2.09 \times 10^{-7} \mathrm{~T} \)
(d) \( 2.09 \times 10^{-8} \mathrm{~T} \)
