Question

VI.Answer the following question. 13.Explain Faraday's experiment of magnet and coil.What factors can be observed when the magnet is replaced by a coil carrying current? What are the conclusions that can be drawn by you from these experiments? State electromagnetic induction with the help of this experiment.​

Answer 1

$\Large\underline{\underline{\red{\purple{\maltese}\; \tt Faraday's \ \ Experiment :- }}}$

When a conductor is moved in a magnetic field or the magnetic field associated with a coil changes then an EMF or electrical current is produced. This EMF is called the induced current in a conductor by continuously changing the magnetic field associated with it. This is called Electromagnetic Induction .

$\large \underline{\boxed{\pink{\tt{ Illustration :- }}}}$

Connect the ends of a coil to a galvanometer . Now move the north pole of the bar magnet towards the coil .

$\textsf {( See the \pink{ attachment one} . ) }$

• We will see that there is a momentary deflection of the galvanometer. This implies the presence of current in the coil $(\sf C_1)$ . The deflection becomes zero at the moment of the motion of the magnet stops.

• If we draw the north pole of the magnet away from the coil then the galvanometer is reflected in the opposite direction as of the first situation.

$\textsf {( See the \pink{ attachment two} . ) }$

• If we don't move the magnet then there will be no deflection shown in the galvanometer.
