A point source of power \( 15 \mathrm{~W} \) is placed at a certain point in the space. The amplitude of magnetic field at a distance of 2 meter from source is:
\( \mathrm{P} \)
(1) \( 5 \times 10^{-8} \mathrm{~T} \)
(2) \( 6 \times 10^{-8} \mathrm{~T} \)
(3) \( 10 \times 10^{-8} \mathrm{~T} \)
(4) \( 1 \times 10^{-8} \mathrm{~T} \)
