    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 :

     \boxed{ \bf \: E =  \dfrac{\Delta \phi}{\Delta t}}

    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.

    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
