Lenz's Law is about conservation of energy. It guarantees that induced currents get their energy from the effect creating the change. As the conductor moves down, the flux increases, so the induced field opposes this which leads to the direction of the Induced current - which in turn shows the direction of the force back on the current.

inductance is comparable to enertia. as enertia opposes motion same inductnce opposes current(electric motion).
