Answer #1

The direction of magnetic force along +x axis

becasue, as th rod slides down the magnetic flux through the loop decreases. so, emf is induced and induced current flows through the loop.

the direction of induced current is as shown in the figure.

so, magnetic force acts along +x axis as shown in figure.
