Magnetic field in a plane electromagnetic wave is given by \( \overrightarrow{B} = B_0 \sin (kx + \omega t) \hat{j} T \). Expression for corresponding electric field will be: Where c is speed of light.
1
\( \overrightarrow {E} = B_0 c \sin (kx + \omega t) \hat{k} \, V/m \)
2
\( \overrightarrow{E} = \dfrac{B_0}{c} \sin (kx + \omega t) \hat{k} \, V/m \)
3
\( \overrightarrow {E} = - B_0 c \sin (kx + \omega t) \hat{k} \, V/m \)
4
\( \overrightarrow{E} = B_0 c \sin (kx - \omega t) \hat{k} \, V/m \)
