So actually your question is "Why Electric Field is generated when Magnetic Field changes with time?"
or why Faraday's Law exists in nature?
Whenever we humans start to reason logically, scientifically, mathematically etc. we start with some Axioms/Postulates etc. So let's e.g.
Marcus is a Man. (Postulate) (We have taken this as truth.)
All men are mortals. (Postulate) (We have taken this as truth.)
=> Marcus is a mortal.
So asking Why Marcus is a mortal? has above two postulates as answer.
But asking Why Marcus is a Man? or Why all men are mortals? is answerless at least in this logic. Because we have to start our logic from some basic truths or something which is assumed to be a truth by observations etc.
e.g. Einstein Special Theory of Relativity has got two postulates. Now asking
"Why laws of nature must be the same in all inertial frame of reference?"
"Why speed of light is constant in every inertial reference frame?
or "Why Einstein and others assume Universe to be Homogeneous, Isotropic etc.?"
"Why Newton's Gravitation was assumed to be a universal Law, though we humans weren't been able to travel in the entire universe (Even we hadn't reached at Moon at that time)?"
Euclid gives 5 postulates for Geometry. All other theorems took these as base.
Hence Faraday's Law works (or EMF induces) because we have seen it in nature without exception.
Although Classical Electromagnetism consists Faradays' Law as a fundamental Law.
But your question is somehow correct and enlightening in terms of looking deep inside the Law.
Hence I am not saying that there can not be other answer to your question in entire Universe.
e.g. Maxwell equation Div B
=0 is fundamental but can be turned to more appropriate physical explanation that "Magnetic Monopoles doesn't exist in nature".
Now "Why magnetic monopoles doesn't exist in nature?" has got answer, "..because we haven't seen any until now."
Similarly Conservation of Energy exist because of Symmetry in time (Ref. Noether's Theorem).
(Again someone may ask "Why time is symmetrical?..because it is observed, so we take it for granted.")
But these are precisely not answers/reasons/causes, but alternative form of the same thing.
