Why is it that the flux linkage does not change instantaneously ?
is it some property of magnetic fields?

what do you know about inductors when a current is applied to them and then what happens when the current is turned off ?
That will go a long way to answering your question

is it some property of magnetic fields?

It's not a property of magnetic fields BUT it does have to do with what is happening with the magnetic field around the inductor

Well, the inductors resist any change in current by applying an opposite emf. But why do they resist ? Is it something like the magnetic field doesn't want to change immediately ?

As Dave has stated, it has NOTHING to do with the magnetic field! You are chasing the wrong culprit.

It has everything to do with Lenz's Law and Faraday's law, i.e. basic E&M field from Maxwell equations. I am hoping that the mentioning of those concepts either will trigger your memory (if you've learned about them before), or direct you to do a search on those principles.
