Expert Answer:

The direction of the magnetic Lorentz force is governed by Right hand thumb rule. According to this rule, if the curl of the fingers describes the cross product (begin mathsize 11px style straight v with rightwards arrow on top end style ×begin mathsize 11px style straight B with rightwards arrow on top end style) then the thumb gives the direction of the force ().

As per this rule, the direction of  is always perpendicular to the plane containing  and.
