The directions of magnetic force and magnetic field lines are shown in the figure.
The direction to find out the magnetic field lines is given by right hand curl rule. If the thumb shows the direction of current, then the curling fingers show the direction of magnetic field lines.
The direction of force can be given by right hand thumb rule, where
Thumb - Direction of magnetic field lines
Forefinger - Magnetic force
Centre finger - Current
Such that forefinger, centre finger and thumb must be at 90 degrees to each other.

Let's choose the "east" direction as positive x-direction. The new velocity of the jet is the vector sum of two velocities: the initial velocity of the jet, which is
along the x-direction
in a direction
north of east.
To find the resultant, we must resolve both vectors on the x- and y- axis:
So, the components of the resultant velocity in the two directions are
So the new speed of the aircraft is:
