a coil of insulated wire is connected to a galvenometer. what would be seen if a bar magnet with its south pole is brought towards one face of the coil is :
1) moved quickly towards it. ?
2) moved quickly away from it ?
3) placed near its one face ?
4) name the phenomena involved ?
5) north pole of the magnet is brought towards the saame face of the coil ?
6) north pole of bar magnet is kept stationary near the same face of the coil ?

Solution

(1) Galvanometer shows deflection in one direction due to induced emf.
(2) Galvanometer shows deflection in opposite direction as that of the earlier.
(3) No deflection is observed due no induced emf.
(4) Electromagnetic Induction
(5) Galvanometer shows deflection in opposite direction when compared to the case of south pole brought towards the face due to induced emf.
(6) No deflection is observed due no induced emf.
