In a DC circuit(Yes, keep going), when current starts to flow, and that current needs a bit of time to stabilize to its maximum value. Since there is change in current(increase) there is an increasing magnetic field, a changing flux... that will induce a -V to the circuit. Eventually when current stabilizes at t0, the induced V due to self inductance = 0 right? But, how does current stabilize when there is that -V opposing it? Would the PS apply more voltage?
