it is wrong, see 12 is the sum of north and south poles but 6 should be the answer!!
Ans 6:
Class : Class 9
IT is not correct .... because they did not ask total number of poles ....it should be A {SIX}
Ans 10:

UTSAV C PATEL from Podar International School SHIVAMOGAClass;It is wrong answer as they did not ask the total number of poles
Ans 14:
Class : Class 9
It is incorrect as there are six north poles and six south poles present in a magnet if it is broken into six pieces

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.
Ans 4:
Class : Class 6
I didnt understand how it is R, can someone explain? Because according to me, the first point of contact is Q, but maybe that's not how it works....
Ans 8:
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.
Ans 9:
Class : Class 8
it has started magnetising from Q SO THATS WHY IT IS TELLING THAT Q WILL BE THE NORTH SEEKING POLE.
Ans 13:
Class : Class 9
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 ..

Ans 15:
Class : Class 7
The answer is P as you can clearly see the iron rod should allow the magnetism to flow like what happens when you chain a nail, even though you are affecting only the top part the whole screw is affected hence proving the answer is wrong
Ans 16:
Class : Class 9
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
Ans 19:
Class : Class 6
As north seeking pole is geographic south pole so R is north seeking pole. so , basically the south pole is the north seeking pole and as the north pole is facing downwards and starting with Q so south pole will be R . Hence, R is the north seeking pole and option C is the correct option.
Ans 21:
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.....
Ans 22:
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.

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 8:
Class : Class 9
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.
