Question

1) Define electromagnetic induction.
2) Two coils P and S are wound over the same iron vote. Coil P is connected to a battery and a key and coil S is connected to a galvanometer. Write your observations when,
a) Current in the coil P is started by closing the key.
b) Current continues to flow in coil P.
c) Current in coil Pis stopped by removing the key. Explain reason.

Answer 1

electromagnetic induction = whenever there is relative motion between conductor as a coil and a magnet ,current is induced in the coil this phenomena is known as electro magnetic induction

a) their will be a momentary deflection in glavanometer connected with coil s

b)no deflection in the galvanometer of coil s

c) their will be a momentary deflection in the galvanometer of coil s

Answer 2

HELLO DEAR

ELECTROMAGNETIC INDUCTION => WHEN A MAGNET IS IN MOTION RELATIVE TO A COIL ATTACHED WITH A GALVANOMETER INDUCE ELECTRIC CURRENT IS SETUP IN THE COIL AND ITS CHANGING MAGNETIC STRENGTH IS CALLED ELECTROMAGNETIC INDUCTION

SORRY FOR ANOTHER

HOPE IT HELPS YOU DEAR FRIEND

THANKS
