(N/A) For a long time,electricity and magnetism were considered separate and unrelated phenomena. In the early $19^{th}$ century,experiments by Oersted,Ampere,and others established that electricity and magnetism are interrelated,showing that moving electric charges produce magnetic fields.
Michael Faraday in England and Joseph Henry in the $USA$,around $1830$,demonstrated that electric currents are induced in closed coils when subjected to changing magnetic fields.
Electromagnetic induction is the phenomenon in which an electric current is generated in a conductor by a varying magnetic field.

Discuss the contribution of different scientists to electromagnetism. Define electromagnetic induction.

According to Faraday's law of electromagnetic induction:

$A$ system $S$ consists of two coils $A$ and $B$. The coil $A$ carries a steady current $I$. The coil $B$ is suspended nearby as shown in the figure. If the system is heated,so as to raise the temperature of the two coils steadily,then:

$A$ rectangular loop of wire $ABCD$ is kept close to an infinitely long wire carrying a current $I(t) = I_0(1 - t/T)$ for $0 \le t \le T$ and $I(t) = 0$ for $t > T$ as shown in the figure. Find the total charge passing through a given point in the loop in time $T$. The resistance of the loop is $R$.
