Confused about inductor polarity

  1. Oct 1, 2016 #1
    So initially S1 and S4 are closed and current flows as seen above.


    After some time S1 and S4 are open and current flows as seen above. Now I am confused about the polarity of the inductor, what if I said the current flows through D1 and D4 instead of D3 and D2 ?, would that be wrong ?

    Inductors do not HAVE a polarity

    wouldn't that be wrong way through the diodes ?

    remember e = L di/dt . That says Polarirty across an inductor reverses when you go from increasing current to decreasing current
