Q. A steady current from a source of emf is passing through a straight conductor from left to right. If the source in switched off, what will be the direction of induced current in the wire?

since the straight conductor has the zero inductance or very less inductance so when the EMF is removed and the wire must be shorted for thr further flow of current .then the inductance try to make the current in same direction as it were flowing. but this not happend for the straight wire as it has very small inductance but this can be observed in the inductor .Regards
