An electromagnetic wave has an electric field given by \( \vec{E}=(9.6 \hat{j}) \sin \left[2 \pi\left\{30 \times 10^6 t-\frac{1}{10} x\right\}\right], x\) and \(t\) are in S.l units. The maximum magnetic field (\(B_0\)) associated with this wave is:
1. \( 3.2\times10^{-8}~\text T\)
2. \( 9.6\times10^{-8}~\text T\)
3. \( 1.7\times10^{-8}~\text T\)
4. \( 10^{-7}~\text T\)
