From right Hand Rule , Let the fingers of your right hand point in the direction of E.  Orient the palm of your hand so that, as you curl your fingers, you can sweep them over to point in the direction of B.  Your thumb points in the direction of E x B
 
So, if E is upwards in the page then magnetic field be in the right direction.
