The magnetic field in a dipole moves from north pole to south pole which means here the direction of magnetic field is in left direction.
Now since the current in the wire part PQ is moving downwards we can use the Lorrentz's force to find the force on the wire. which is given as -
F = I(dLxB)
where IdL is the current element vector and B is the magnetic field vector
Now the direction of F can be given by using right hand Thumb rule which indicates for the given question that the force is into the screen. Thus Option (a) is correct.

When the switch is closed in the circuit shown in the sketch in Figure 22-7
When the switch is closed in the circuit shown in the sketch in Figure 22-7, the wire between the poles of the horseshoe magnet deflects upward. From this you can conclude that the left end of the magnet is A) a south magnetic pole C) not contributing to the wire's deflection. B) a north magnetic pole. D) a magnetic monopole
