    1. The problem statement, all variables and given/known data

    2 movable conducting bars on a conducting rail with a uniform magnetic field heading inside the paper , what will happen to bar 2 if we move bar 1 to the left with a velocity v ?

    3. The attempt at a solution
    i think that a current will be induced in bar 2 and pass to bar 1 via the rail , as a result , the magnetic field will affect bar 1 with a magnetic force and move it to the left (force on a current carrying wire) , but will there be a repel force between the two bars because a current passes through both of them (force between two parallel current-carrying wires) , and will that force stop bar 1 from moving left ?
