Faraday's law of induction can be said to be a basic law in relation to electromagnetism predicting the manner in which a magnetic field shall be able to interact with any specific electric circuit in order to produce any specific electromotive force, which can be said to be a phenomenon that is actually known to be the electromagnetic induction. It can be regarded as a law affirming that when the specific magnetic flux connecting any circuit changes, an electromotive force can be said to be induced in the specific circuit comparative to the rate of the change of the specific flux linkage.
Faraday’s law of the induction, in the subject of physics, can be said to be a quantitative relation, which expresses that any changing or altering magnetic field actually induces or brings a voltage in any circuit, which had been developed based upon the specific experimental observations that had been made in the year of 1831 by the famous English scientist named Michael Faraday.

When any magnet is shifted into any coil of wire, changing or altering the magnetic field as well as the magnetic flux with the help of the coil, any specific voltage shall be generated in the specific coil as per Faraday's Law. In the particular instance or example, when the specific magnet is actually shifted into the specific coil, the galvanometer actually deflects towards the left as a response to the cumulative field.
Faraday's first law in relation to electromagnetic induction states that whenever any specific conductor is actually placed in any varying or changing magnetic field, a specific electromotive force is actually induced. In a similar manner, if the specific conductor circuit is actually closed, any current is actually induced, which is known to be the induced current. Faraday’s second law in relation to electromagnetic induction actually states that the specifically induced emf in a particular coil can be said to be equal to the particular rate of the change of the flux linkage.

Consider any magnet approaching any coil. Consider 2-time cases T1 as well as T2.
Flux connection with the specific coil during the time T1 is provided by NΦ1.
Flux connection with the specific coil during the time T2 is provided by NΦ2
Change in the specific flux connection is provided by
N(Φ2 – Φ1)
One should consider this specific change in the flux linkage as
Φ = Φ2 – Φ1
Therefore, the change in the flux linkage is provided by NΦ
The rate of the change of the flux linkage is provided by NΦ/t
Taking the specific derivative of the above-mentioned equation, one shall get N dΦ/dt
As per Faraday’s second law in relation to electromagnetic induction, it is known that the specifically induced emf in any coil shall be equal to the specific rate of the change of the flux linkage. Therefore,
Considering Lenz’s law,
From the above-mentioned equation, one shall be able to conclude the following
From the particular experimental observations, it was concluded by Faraday that a specific emf is actually induced when the specific magnetic flux all over the coil changes or alters with time. Hence, Faraday's first law in relation to electromagnetic induction actually states that whenever any conductor is actually placed in any varying magnetic field, a specific electromotive force can be said to have been induced.
The following can be said to be the fields where Faraday’s law finds applications:
Answer: It is important because Faraday's law describes the manner in which any changing magnetic flux actually induces any electric field.
Answer: Faraday's first law in relation to electromagnetic induction states that whenever any specific conductor is actually placed in any varying or changing magnetic field, a specific electromotive force is actually induced.
Answer: Faraday’s second law in relation to electromagnetic induction actually states that the specifically induced emf in a particular coil can be said to be equal to the particular rate of the change of the flux linkage.
Answer: Electric generators, metal detectors, credit cards, computer hard drives, and others.
Answer: Electromotive force or electromagnetic force.
