Two long straight parallel wires P and Q carry currents into the plane of the paper, as shown in the figure below.
The current in P is 
and the current in Q is 
.
On the figure above, draw an arrow to show the direction of the magnetic field at wire Q due to the current in wire P. Label this arrow B.
On the figure above, draw another arrow to show the direction of the force acting on wire Q due to the current in wire P. Label this arrow F.
