1. ELECTROMAGNETIC INDUCTION:

   • It refers to current produced in a circuit due to formation of EMF (electro-motive force) with respect to a varying magnetic field and magnetic flux.

   • It was first discovered by Michael Faraday and mathematically postulated by James Clerk Maxwell.

   • The EMF produced can be mathematically written as :

   [tex] \boxed{ \bf \: E = \dfrac{\Delta \phi}{\Delta t}}[/tex]

   Now, current in circuit hence depends upon 2 factors:

   • Rate of change of magnetic flux: Higher the rate change, higher will be the EMF and higher will be the current.

   • Number of coils of wire around the magnetic field: Higher the number of coils, higher is the current.

   Hope It Helps.

2. Answer:

   Two factors on which induced e.m.f. depends on electromagnetic induction are as follows: 1) The strength of the magnetic field: It is directly proportional to induced e.m.f. 2) The number of coils: It is directly proportional to induced e.m.f
