These are two different circuits. First circuit = Inductor + battery Second circuit = Resistor + battery At t=0+ (right when the switch was closed), the first circuit doesn't have current. The second does. The first circuit doesn't even have current going out of the battery - at all - it means...

Thanks Claude. Your ego has very big potential. You are still trying to explain something that hasn't been my direct question. P.S I'm not trying to lecture anybody. If you do, please pay attention to other's questions rather than explaining unrelated information (and arguing that basic laws in...

Thanks for the link but my question was different. I asked what happened at t=0+, when no current is flowing through the inductor, so no magnetic field is generated (it is but it doesn't happen because of the current flow, but due to the potential difference by connecting a source with some...

I order to oppose change in current at t=0, the inductor generates negative voltage. If you close the switch for a long period of time then remove the battery, the inductor would generate (for a limited time), the same current the battery was generating since it doesn't like a sudden change in...

Consider the following: You have a circuit with an inductor and a battery. You have an open switch, that was open for gazillion years. The inductor is "uncharged", meaning has no stored magnetic field. Then, you close the switch. At time t=0+, right at the moment you closed the switch, the...
