The force on the right-hand conductor is due to the iteration of the external magnetic field and the magnetic field produced by that induced current.
If that was the only force which was acting to the right-hand conductor, the conductor would slow down ie $v$ would decrease and the kinetic energy of the conductor would be decreasing.
In terms of energy that loss in kinetic energy of the conductor would equal the electrical energy produced bu the arrangement which in turn would produce heat due to ohmic heating.  
In order to keep the right hand conductor moving at constant speed an external force, equal in magnitude and opposite in direction to the force due to the interaction of the external magneticManchester Maccabi beaten again

Manchester Maccabi 1st suffered their second consecutive defeat, going down 3-2 against Charlestown.

In the only game in all five divisions of the Eccles League to survive the heavy rain the North West had experienced in the previous week, Maccabi , for the second week in a row finished losers after playing the better football and creating more chances than their opponents.

Charlestown always pose a severe test of any Maccabi side, and manager Scott McGarvey chose to change the set up of the team by playing three central midfielders with the two wide men of Emile Davidson and Rafi Leker supporting Leor Sidle alone up front. This change to the usual 4-4-2 system took 15 minutes of the game to adapt to, but once
