Electromagnetic Wave Magnetic Field

A plane electromagnetic wave is moving in free space with velocity c = 3 × 10⁸ m/s and its electric field is given as $\vec E = 54\sin \left( {kz - \omega t} \right)\hat j\,\,\,V/m,$ where $\hat j$ is the unit vector along y-axis. The magnetic field vector $\vec B$ of the wave is :
