why initially inductor will not allow current, it can be proved theoritically can you plz give me a pratical reason.

at time t=0, first the differential amount of current enters as it would enter without any indouctor , but, on reaching it there would be opposite indouced emf due to sudden variation of current in the inductor. this opposing emf reduces the emf of the battery as an effect. This process continues and current enters like watre in a squeesed tube which slowly allows current thru small hole kind.

Get the feeling??

Once think about it.
