welcome to my channel education this is
Srinivas today topic is this law of
electromagnetic induction was found by
Michael Faraday he organized a leading
wire according to the setup given
underneath connected to a gadget to
gauge the voltage over the circuit so
when a bar magnet passes through the
snaking the voltage is measured in the
circuit the importance of this is a way
of producing electrical energy in a
circuit by using magnetic fields and not
just batteries anymore
the machines like generators
transformers also the motors work on the
principle of electromagnetic induction
first law whenever a conductor is placed
in a varying magnetic field EMF induces
and this F is called an induced EMF and
if the conductor is a closed circuit
then the induced current flows through
it second law the magnitude of the
induced EMF is equal to the rate of
change of flux linkages based on his
experiments we now have Faraday's law of
electromagnetic induction according to
which the amount of voltage induced in
the coil is proportional to the number
of turns and the changing magnetic field
of the coil so now the induced voltage
is as follows P equals n
