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.

A conducting rod of mass m and resistance R, slides with no
friction on an horizontal rail of width l and negligible
resistance. At t=0, the rod passes O with a velocity v0. The rail
is closed from one side only, so that the rod actually forms a
closed circuit. A constant magnetic field B is present everywhere,
perpendicular to the plane of the rail. v0, m , l, R and B are

A conducting bar slides without friction on two parallel horizontal rails that are 50 cm apart and connected by a wire at one end. The resistance of the bar and the rails is constant and equal to 0.10 0. A uniform magnetic field is perpendicular to the plane of the rails. A 0.080-N force parallel to the rails is required to keep the bar moving at a constant speed of 0.50 m/s. What is the magnitude of the magnetic field...
