Yes it should be A ......because it is not possible that some of the iron bar is magnet and some is iron ....in the given figure starting of the stroke is point is Q but before that is point P which is starting of the rod so the CORRECT answer is A ..
Class : Class 10
The magnet first makes contact with Q, so, it is the North Pole of the magnet
Class : Class 8
it has started magnetising from Q SO THATS WHY IT IS TELLING THAT Q WILL BE THE NORTH SEEKING POLE.
Class : Class 7
In the above process of magnetisation, the magnet makes its first contact with the iron rod on place R, so R would be the North pole of the magnetised iron bar.
Class : Class 6
A IS TH CORRECT ANSWER. In the figure they started stoking the iron piece from point P which is the starting of the iron rod. so the correct answer is A.....
Class : Class 7
At first, I also thought that it will be A but if you see the figure closely, you can see that the magnet first comes in contact with point Q, it is rubbed till R and is then lifted at R point. So, Point Q would be the north pole and the point R would be the south pole
Class : Class 7
Sorry R would be the south pole because of the reason:Q becomes the North pole, and R, where the magnet is lifted becomes the south pole.
Class : Class 8
If you clearly notice, the arrow is first coming in contact with Part Q, and the arrow is above in Part P. First, the magnet comes in contact with part Q, so when the iron rod is magnetised, Part Q will be North pole.
Class : Class 6
The correct answer is (B),Q because the magnetic contact starts on Q and not on P.

If the filament of bulb Q is fused then the circuit is not being completed because the electrons won't be able to reach the positive terminal as they would be stopped by the broken filament and electricity won't be able to pass through the filament to the negative terminal and due to the two cases that a circuit has to be completed for electricity to move and second one given it is proven that option 'B' is the correct option instead of 'A' 'C' or ' D'
Ans 5:
Class : Class 7
answer should be c as the wire is connecting to p and r ALSO IF THE FILAMENT IS BROKEN ONLY Q CAN NOT LIGHT UP.
